BSP for beagleboard xm, beaglebone (original aka white), and beaglebone black.
|
||||
|
||||
original beagleboard isn't tested.
|
||||
|
||||
wiki: http://www.rtems.org/wiki/index.php/Beagleboard
|
||||
|
||||
1. *** CONFIGURING ************
|
||||
|
||||
bsp-specific build options in the environment at build time:
|
||||
CONSOLE_POLLED=1 use polled i/o for console, required to run testsuite
|
||||
CONSOLE_BAUD=... override default console baud rate
|
||||
|
||||
BSPs recognized are:
|
||||
beagleboardorig original beagleboard
|
||||
beagleboardxm beagleboard xm
|
||||
beaglebonewhite original beaglebone
|
||||
beagleboneblack beaglebone black
|
||||
|
||||
Currently the only distinction in the BSP are between the beagleboards and
|
||||
the beaglebones, but the 4 names are specified in case hardware-specific
|
||||
distinctions are made in the future, so this can be done without changing the
|
||||
usage.
|
||||
|
||||
|
||||
2. *** BUILDING ************
|
||||
|
||||
To build BSPs for the beaglebone white and beagleboard xm, starting from
|
||||
a directory in which you have this source tree in rtems-src:
|
||||
|
||||
$ mkdir b-beagle
|
||||
$ cd b-beagle
|
||||
$ ../rtems-src/configure --target=arm-rtems4.11 --enable-rtemsbsp="beaglebonewhite beagleboardxm"
|
||||
$ make all
|
||||
|
||||
This should give you .exes somewhere.
|
||||
|
||||
Then you need 'mkimage' to transform a .exe file to a u-boot image
|
||||
file. first make a flat binary:
|
||||
|
||||
$ arm-rtems4.11-objcopy $exe -O binary $exe.bin
|
||||
$ gzip -9 $exe.bin
|
||||
$ mkimage -A arm -O rtems -T kernel -a 0x80000000 -e 0x80000000 -n RTEMS -d $exe.bin.gz rtems-app.img
|
||||
|
||||
All beagles have memory starting at 0x80000000 so the load & run syntax is the same.
|
||||
|
||||
3. *** BOOTING ************
|
||||
|
||||
Then, boot the beaglebone with u-boot on an SD card and load rtems-app.img
|
||||
from u-boot. Interrupt the u-boot boot to get a prompt.
|
||||
|
||||
Set up a tftp server and a network connection for netbooting. And to
|
||||
copy rtems-app.img to the tftp dir. Otherwise copy the .img to the FAT
|
||||
partition on the SD card and make uboot load & run that.
|
||||
|
||||
4. *** BEAGLEBONES ************
|
||||
|
||||
(tested on both beaglebones)
|
||||
|
||||
Beaglebone original (white) or beaglebone black netbooting:
|
||||
|
||||
uboot# setenv ipaddr 192.168.12.20
|
||||
uboot# setenv serverip 192.168.12.10
|
||||
uboot# echo starting from TFTP
|
||||
uboot# tftp 0x80800000 rtems-app.img
|
||||
uboot# dcache off ; icache off
|
||||
uboot# bootm 0x80800000
|
||||
|
||||
Beaglebone original (white) or beaglebone black from a FAT partition:
|
||||
|
||||
uboot# fatload mmc :1 0x80800000 ticker.img
|
||||
uboot# dcache off ; icache off
|
||||
uboot# bootm 0x80800000
|
||||
|
||||
4. *** BEAGLEBOARD ************
|
||||
|
||||
(tested on xm)
|
||||
|
||||
For the beagleboard the necessary commands are a bit different because
|
||||
of the ethernet over usb:
|
||||
|
||||
uboot# setenv serverip 192.168.12.10
|
||||
uboot# setenv ipaddr 192.168.12.62
|
||||
uboot# setenv usbnet_devaddr e8:03:9a:24:f9:10
|
||||
uboot# setenv usbethaddr e8:03:9a:24:f9:11
|
||||
uboot# usb start
|
||||
uboot# echo starting from TFTP
|
||||
uboot# tftp 0x80800000 rtems-app.img
|
||||
uboot# dcache off ; icache off
|
||||
uboot# bootm 0x80800000
|
||||
|
||||
4. *** SD CARD ****************
|
||||
|
||||
There is a script here that automatically writes an SD card for any of
|
||||
the beagle targets.
|
||||
|
||||
Let's write one for the Beaglebone Black. Assuming your source tree is
|
||||
at $HOME/development/rtems/rtems-src and your bsp is built and linked
|
||||
with examples and installed at $HOME/development/rtems/4.11.
|
||||
|
||||
% cd $HOME/development/rtems/rtems-src/c/src/lib/libbsp/arm/beagle/simscripts
|
||||
% sh sdcard.sh $HOME/development/rtems/4.11 $HOME/development/rtems/b-beagle/arm-rtems4.11/c/beagleboneblack/testsuites/samples/hello/hello.exe
|
||||
|
||||
The script should give you a whole bunch of output, ending in:
|
||||
|
||||
Result is in bone_hello.exe-sdcard.img.
|
||||
|
||||
There you go. dd that to an SD card and boot!
|
||||
|
||||
The script needs to know whether it's for a Beagleboard xM or one of the
|
||||
Beaglebones. This is to know which uboot to use. It will detect this
|
||||
from the path the executable is in (in the above example, it contains
|
||||
'beagleboneblack'), so you have to specify the full path.
|
||||
|
||||
|
||||
Good luck & enjoy!

To run RTEMS from scratch (without any other bootcode) on the beagles,
|
||||
you can comfortably load the executables over JTAG using gdb. This is
|
||||
necessarily target-specific however.
|
||||
|
||||
1. BBXM
|
||||
|
||||
- For access to JTAG using openocd, see simscripts/bbxm.cfg.
|
||||
- openocd then offers access to gdb using simscripts/gdbinit.bbxm.
|
||||
- start openocd using bbxm.cfg
|
||||
- copy your .exe to a new dir and that gdbinit file as .gdbinit in the same dir
|
||||
- go there and start gdb:
|
||||
$ arm-rtems4.11-gdb hello.exe
|
||||
- gdb will invoke the BBXM hardware initialization in the bbxm.cfg
|
||||
and load the ELF over JTAG. type 'c' (for continue) to run it.
|
||||
- breakpoints, C statement and single-instruction stepping work.
|
||||
|
||||
2. beaglebone white
|
||||
|
||||
This has been tested with openocd and works but not in as much detail as for
|
||||
the BBXM yet (i.e. loading an executable from scratch).

To build and run the tests for this BSP, use the RTEMS tester.
|
||||
The necessary software can be built with the RTEMS source builder.
|
||||
|
||||
To build the BSP for testing:
|
||||
- set CONSOLE_POLLED=1 in the configure environment, some tests
|
||||
assume console i/o is polled
|
||||
- add --enable-tests to the configure line
|
||||
|
||||
1. Qemu
|
||||
|
||||
Linaro Qemu can emulate the beagleboard xm and so run all regression
|
||||
tests in software. Build the bbxm.bset from the RTEMS source builder and
|
||||
you will get qemu linaro that can run them. There is a beagleboardxm_qemu
|
||||
bsp in the RTEMS tester to invoke it with every test.
|
||||
|
||||
2. bbxm hardware
|
||||
|
||||
This requires JTAG, see README.JTAG. Use the beagleboardxm bsp in the
|
||||
RTEMS tester. It starts gdb to connect to openocd to reset the target
|
||||
and load the RTEMS executable for each test iteration.

Pulse Width Modulation subsystem includes EPWM, ECAP , EQEP. There are
|
||||
different instances available for each one. For PWM there are three
|
||||
different individual EPWM module 0 , 1 and 2. So wherever pwmss word is
|
||||
used that affects whole PWM sub system such as EPWM, ECAP and EQEP. This code
|
||||
has only implementation Non high resolution PWM module. APIs for high
|
||||
resolution PWM has been yet to develop.
|
||||
|
||||
For Each EPWM instance, has two PWM channels, e.g. EPWM0 has two channel
|
||||
EPWM0A and EPWM0B. If you configure two PWM outputs(e.g. EPWM0A , EPWM0B)
|
||||
in the same device, then they *must* be configured with the same frequency.
|
||||
Changing frequency on one channel (e.g EPWMxA) will automatically change
|
||||
frequency on another channel(e.g. EPWMxB). However, it is possible to set
|
||||
different pulse-width/duty cycle to different channel at a time. So always
|
||||
set the frequency first and then pulse-width/duty cycle.
|
||||
|
||||
For more you can refer :
|
||||

|
||||
|
||||
Pulse Width Modulation uses the system frequency of Beagle Bone Black.
|
||||
|
||||
System frequency = SYSCLKOUT, that is, CPU clock. TBCLK = SYSCLKOUT(By Default)
|
||||
SYCLKOUT = 100 MHz
|
||||
|
||||
Please visit following link to check why SYSCLKDIV = 100MHz:
|
||||
https://groups.google.com/forum/#!topic/beagleboard/Ed2J9Txe_E4
|
||||
(Refer Technical Reference Manual (TRM) Table 15-41 as well)
|
||||
|
||||
To generate different frequencies with the help of PWM module , SYSCLKOUT
|
||||
need to be scaled down, which will act as TBCLK and TBCLK will be base clock
|
||||
for the pwm subsystem.
|
||||
|
||||
TBCLK = SYSCLKOUT/(HSPCLKDIV * CLKDIV)
|
||||
|
||||
|----------------|
|
||||
| clock |
|
||||
SYSCLKOUT---> | |---> TBCLK
|
||||
| prescale |
|
||||
|----------------|
|
||||
^ ^
|
||||
| |
|
||||
TBCTL[CLKDIV]----- ------TBCTL[HSPCLKDIV]
|
||||
|
||||
|
||||
CLKDIV and HSPCLKDIV bits are part of the TBCTL register (Refer TRM).
|
||||
CLKDIV - These bits determine part of the time-base clock prescale value.
|
||||
Please use the following values of CLKDIV to scale down sysclk respectively.
|
||||
0h (R/W) = /1
|
||||
1h (R/W) = /2
|
||||
2h (R/W) = /4
|
||||
3h (R/W) = /8
|
||||
4h (R/W) = /16
|
||||
5h (R/W) = /32
|
||||
6h (R/W) = /64
|
||||
7h (R/W) = /128
|
||||
|
||||
These bits determine part of the time-base clock prescale value.
|
||||
Please use following value of HSPCLKDIV to scale down sysclk respectively
|
||||
0h (R/W) = /1
|
||||
1h (R/W) = /2
|
||||
2h (R/W) = /4
|
||||
3h (R/W) = /6
|
||||
4h (R/W) = /8
|
||||
5h (R/W) = /10
|
||||
6h (R/W) = /12
|
||||
7h (R/W) = /14
|
||||
|
||||
For example, if you set CLKDIV = 3h and HSPCLKDIV= 2h Then
|
||||
SYSCLKOUT will be divided by (1/8)(1/4). It means SYSCLKOUT/32
|
||||
|
||||
How to generate frequency ?
|
||||
|
||||
freq = 1/Period
|
||||
|
||||
TBPRD register is responsible to generate the frequency. These bits determine
|
||||
the period of the time-base counter.
|
||||
|
||||
By default TBCLK = SYSCLKOUT = 100 MHz
|
||||
|
||||
Here by default period is 1/100MHz = 10 nsec
|
||||
|
||||
Following example shows value to be loaded into TBPRD
|
||||
|
||||
e.g. TBPRD = 1 = 1 count
|
||||
count x Period = 1 x 1ns = 1ns
|
||||
freq = 1/Period = 1 / 1ns = 100 MHz
|
||||
|
||||
For duty cycle CMPA and CMPB are the responsible registers.
|
||||
|
||||
To generate single with 50% Duty cycle & 100MHz freq.
|
||||
|
||||
CMPA = count x Duty Cycle
|
||||
= TBPRD x Duty Cycle
|
||||
= 1 x 50/100
|
||||
= 0.2
|
||||
|
||||
The value in the active CMPA register is continuously compared to
|
||||
the time-base counter (TBCNT). When the values are equal, the
|
||||
counter-compare module generates a "time-base counter equal to
|
||||
counter compare A" event. This event is sent to the action-qualifier
|
||||
where it is qualified and converted it into one or more actions.
|
||||
These actions can be applied to either the EPWMxA or the
|
||||
EPWMxB output depending on the configuration of the AQCTLA and
|
||||
AQCTLB registers.
|
||||
|
||||
List of pins for that can be used for different PWM instance :
