[ECOS] powerpc8270 exception management and redboot and ecos interaction
Fri Jun 15 12:07:00 GMT 2007
I use redboot and an ecos application on a powerpc 8270 board.
1 - powerpc exception management
I use a function _reset developped on our hardware platform that made
an exception (parity error) : this exception provoque the hard reset of
the 8270:can you tell me where is the source that treat this exception.
the code that made this exception is:
unsigned long hid0, int_state;
// Need interrupts off to force checkstop
IMM->clocks_rmr |= 0x01; // Checkstop Reset Enable
// Force a checkstop by turning on parity which is not implemented
hid0 |= 0x30000000;
while (1) ;
2 - reboot and ecos interaction
- Where is the Dynamic memory allocation zone for redboot (if any) and
the ecos application allocation : is that the same? ,
if yes how can this work ?
if not where can we see where is mapped the zone for each?
- Does the ecos application call redboot after the appication is started?
If yes , What part of the ecos application can call the flash_get_config
function with type CONFIG_BOOL and key "info_console_force"?
Thanks for your help
