Vybrid Nand-Flash

[faigner]

Hello,

I'm running Linux on a phycorePCM-052 board from NAND-flash. This is working so far. But for easier flashing and updating, I want to flash U-Boot and Kernel by Linux. I was trying to use nandwrite, flashcp, cp, cat, dd and mtd_debug write to copy it to the correct Position. But it's still not working.

Am I doing something wrong or isn't it working so far?

I'm using U-Boot 2012.11 and Kernel 3.0.15.

Another Problem is, that I'm not able to save the U-Boot environment to the NAND-Flash. It always tries to laod it from the mmc and fails if no card is inserted.

Thank you in advance

Hi Florian,

In case you want to boot from NAND flash you need to configure the image and add the corresponding header to the image so the Boot ROM code fetches the u-boot image correctly.

This can be useful for you Re: Vybrid NAND boot
