Can't start redboot in RAM mode

Can't start redboot in RAM mode

[EE89 student]

Hi
i have a modified ixdp425 board and redboot can run on it with ROM and ROMRAM mode
but after i load the redboot[RAM].bin into memory and trying to execute "go"
,then crash.

here is how i generate the bin file
./ecosconfig new ${Board}_npe redboot
./ecosconfig import
${ECOS_REPOSITORY}/hal/arm/xscale/${Board}/current/misc/redboot_RAM.ecm
./ecosconfig import
${ECOS_REPOSITORY}/hal/arm/xscale/${Board}/current/misc/no_eeprom.ecm
./ecosconfig tree

make


and i already change the settings in
packages/hal/arm/xscale/ixdp425/current/include/pkgconf/
to fit my board
is the crash resulted from my wrong settings? but it works on ROM and ROMRAM mode.

best regards
Blair

Try connecting gdb and see what it says about the crash.

Are you sure Redboot RAM has been linked to run at 0x03000000. It is
rather high in memory. Normally it goes much lower. Try loading the
elf or srec so you don't need to use -b and -r. Redboot itself will
decide where in memory to load RedBoot RAM.
