Just a guess (I doubt, but). It may be bus width issue or it may be a bus timing... It seems for me, there is an additional place to get info in HAL setup: hal/arm/lpc24xx/ea2468/current/src/ea2468_misc.c BTW, you can build eCos `flash1' test and walk through out SST flash init sections in GDB (using the built RedBoot without FLASH support): ;# chdir in a suitable place ecosconfig new ea2468 ecosconfig add flash ecosconfig tree make make -C io/flash/current tests arm-eabi-nm install/tests/io/flash/current/tests/flash1|grep flash It's good to know for break points (useful bps: cyg_flash_get_info, cyg_flash_init). Then try to investigate arm-eabi-gdb -nx install/tests/io/flash/current/tests/flash1 Sergei -- > Thanks, > Viren > > > > > > Please, do not top-post! > > http://en.wikipedia.org/wiki/Top_posting > > > > On Wed, Feb 24, 2010 at 05:02:09AM -0600, viren.dobar...@aftek.com wrote: > >> hi, > >> I check in sst_init function but my prog don't reach there. > >> so, i debug whole code and findout from where it generates error. > >> > >> it returns from cyg_"flash_init function" from > >> "ecos-3.0/packages/io/flash/v3_0/src/flash.c". > >> > >> In cyg_flash_init() function: > >> > >> #if (1 == CYGHWR_IO_FLASH_DEVICE) > >> // Make sure there is one device, otherwise we could end up > >> // accessing a non-existent cyg_flash_dev structure. > >> > >> if (&(cyg_flashdevtab[0]) == &cyg_flashdevtab_end) { > >> return CYG_FLASH_ERR_INVALID; > >> } > >> > >> >From above loop, it always return CYG_FLASH_ERR_INVALID. > >> > >> so that's why i get error given below. > >> FLASH: driver init failed: Invalid FLASH address. > >> > >> how to solve this error? > > > > As Uwe said, you have to check the real Manufacturer/Device IDs for your > > flash parts. > > > > So, first, take a glass and know what is "your" SST flash IC variant > > is fitted on the board.
