Re: [ECOS] Re: Flash support for ea2648 target

[viren dot dobariya at aftek dot com]

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?
please reply me.

Thanks,
Viren
