NAND boot on OMAP2430 SDP GP

NAND boot on OMAP2430 SDP GP

[Ling.Alex]

Dear All,

I’m working on an OMAP2430 SDP v1.1 GP device and I have to implement booing OMAP2430 from on board NAND flash. According to the information I gathered from linux.omap.com, I prepared x-load and sign it with CSST tool v1.4, which adds 8-bytes head (image size + Internal SRAM load address (0x40204000) info to the raw image. Then I flash it to the NAND flash block 0~3 via u-boot’s command “nand write.jffs2”.

But it seemed the x-load was not copied to SRAM by the ROM code of OMAP2430 when I configured the SDP for NAND booting. Is there anything missing for NAND booting for OMAP2430? Any advices will be appreciated.

 

 

For NAND booting, I set the DIP switch of SDP as following:

S8

1-ON           2-ON            3-OFF

S9

1-ON           2-ON            3-OFF

 

 

 

Best regards,

Alex

Wrong. Use csst to flash the x-loader to offset 0. u can read the
userguide on how to do that.
