We have a custom board based on imx27 & we want to boot the kernel from
flash. But the flash we have is Intel Strata P30 ( JS48F4400P0VB00S). We
are modifying the redboot which comes with imx27ADS reference board. We want
to know which file we need to modify?
Any body has successfully able to boot kernel from this flash using redboot
on any other board
Thanks in advance
Regards
Praveen

I think the P30 is a bit odd. Take a look at:

I'm using the same patch on a ep93xx based board using P30 flash. Works
great for me.
The only problem I found in the patch is in flash_hwr_init() the first:
+ __strata_info.base1 = (void *)CYGNUM_FLASH_BASE;
Should be removed. The __strata.info is only available #ifndef
CYGOPT_FLASH_IS_BOOTBLOCK. The .base1 is actually set correctly a bit
later in the code.
Regards,
Hartley

We are using customized arm ADS imx27 board.
Got the redboot source with board.
We are using JS48F4400P0VB00S intel nor strataflash 64MB.
Redboot what we had got has the support for Spansion Nor flash size 64MB ,
it is working for the reference board.
But in our board we have the Intel strata flash.
Can anybody explain where to change in the redboot so that it will take the
IntelStrata flash instead of Spansion flash
Thanks in advance
Regards
Praveen
