i.MX25 NAND status

i.MX25 NAND status

[Eric Bénard]

Hi,

What is the status of current barebox on i.MX25 using NAND boot ?

At the first try, it doesn't compile with CONFIG_NAND_IMX_BOOT enabled 
as imx_nand_load_image wasn't updated in 
board/freescale-mx25-3-stack/3stack.c
-       imx_nand_load_image((void *)TEXT_BASE, 256 * 1024, 2048, 16384);
+       imx_nand_load_image((void *)TEXT_BASE, 256 * 1024);

I've loaded barebox in ram using a JTAG and the NAND flash is properly 
detected but the badblock scan works only if the NAND was previously 
initialised by the JTAG and gives differents results at each run which 
seems to indicate something is wrong in the setup.

The platform I'm testing is a i.MX257 TO 1.1 using a 3.3V 8bits width 2k 
page size 2Gb NAND from Micron (MT29F2G08AAD).

Thanks,

Eric

We have it running from NAND on a custom board here, but I assume the
mainline might not have all necessary patches. As we went to the custom
hardware relatively early, nobody took the time to polish the PDK port.

However, most of our staff is on holiday right now, so we can check next
week.

OK, I managed to get the MX25 NAND boot working using the 
CONFIG_ARCH_IMX_INTERNAL_BOOT option (with the proper DCD table for my 
board low level init).
I'll clean our board support and send it to the list in January (at 
least I hope so ;-).

Thanks,
Eric
