Simple BSP for the TX3904 simulator built into gdb.
|
||||
|
||||
Simulator Invocation
|
||||
====================
|
||||
The following is not 100% correct since it does not work. :)
|
||||
|
||||
target sim --board=jmr3904pal --memory-region 0xffff8000,0x900 \
|
||||
--memory-region 0xffffe000,0x4 --memory-region 0xb2100000,0x4
|
||||
--memory-region 0x8800000,0x100000 -memory-region 0x80000000,0x40000 \
|
||||
--memory-region 0xfffff300,0x10
|
||||
|
||||
Status
|
||||
======
|
||||
This BSP is not working. It gets to the point where the
|
||||
console_outbyte_polled() routine is called during printf
|
||||
and it locks up checking for a status bit. This is probably
|
||||
a simulator initialization issue related to the setup command.
|
||||
As of 25 Nov 2000, email was sent to the gdb and newlib maintainers
|
||||
asking for advice.
