- Add 'rtems_shell_init_environment()' so a user can create the
shell environment without needing to run a shell.
- Move 'rtems_shell_lookup_topic', 'rtems_shell_can_see_cmd',
and 'rtems_shell_execute_cmd' from the internal interface to
the public interface.
Closes#3104.
Right after a "msr basepri_max, %[basepri]" instruction an interrupt
service may still take place (observed at least on Cortex-M7). However,
pendable service calls that are activated during this interrupt service
may be delayed until interrupts are enable again. The
_ARMV7M_Pendable_service_call() did not check that a thread dispatch is
allowed. Move this test from _ARMV7M_Interrupt_service_leave() to
_ARMV7M_Pendable_service_call().
Close#3060.
Remove forced overwrite which leads to file data corruption. The logic
to determine a forced overwrite was fundamentally broken. For simplity,
disable this feature.
Close#2622.
It is all right in case the result uses the full destination buffer.
Without this fix the handling of a maximum 8.3 short file name is
broken.
Close#2928.
In canonical mode, the raw input buffer or the canonical buffer may
overflow without an end of line. Avoid an infinite loop in this case.
Update #2915.
The second FAT entry contains a bit to indicate if the FAT32 filesystem
is not dirty and a bit to indicate if there was no IO error. Set both
bits for a fresh filesystem. This prevents a warning if mounted on
Windows.
Update #2913.
The CPU_CACHE_LINE_BYTES has been introduced after 4.11 branch
fork and is not available for all architectures on RTEMS 4.11.
Use of rtems_cache_get_maximal_line_size() is more descriptive
choice. The min/max data/instruction cache line size is not critical
there, value is used for optimization only to use single operation
for decently following sections.
The configuration is specific for TMS570LS3137 based HDK.
Pins configuration can be easily changed in
rtems/c/src/lib/libbsp/arm/tms570/hwinit/init_pinmux.c
file.
The list tms570_selftest_par_list in the file
rtems/c/src/lib/libbsp/arm/tms570/hwinit/bspstarthooks-hwinit.c
specifies peripherals which health status is examined
by parity self-test at BSP start-up. It can be easily
modified for other TMS570 family members variants same
as the selection of other tests in bspstarthooks-hwinit.c.
Generated header file ti_herc/reg_spi.h contains complete registers
and fields set for Ti MibSPI peripheral.
Care has to be taken that only TMS570_SPI1, TMS570_SPI3 and TMS570_SPI5
are of this complete multibuffer type. TMS570_SPI2 and TMS570_SPI4
have substantial part of registers removed but else they are compatible.
The rtems_monitor_task() setups/updates termios attributes
of the opened TTY and if there is ongoing some other output
it leads to the stuck.
It would be better to use some termios API function which
would call drainOutput() in rtems/cpukit/libcsupport/src/termios.c.
But functionality is not accessible outside of core termios
implementation.
The loop waiting for last character to be sent has to be there anyway
because hardware does not provide Tx machine/shift register empty
interrupt.
Closes#2794
The symbol can be used by bsp_start_hook_0 when complete
RAM memory is initialization and overwritten during BSP
self-test. The test overwrites even memory used to store
return address / link register and regular resturn from
bsp_start_hook_0 is not possible then.
This is minimized version of mainline patch
arm/raspberrypi: move MMU in front of application image to respect variable memory size.
plus correction which has been part of other mainline patches.
This is end of series which allows 4.11 to boot on Raspberry Pi.
