From: abraham.varricatt@vvdntech.com Hello,
Thanks to the help I obtained on this mailing list, I've been able to customize u-boot (2013.10 release) to work on a custom omap4460 board. Schematically, it's similar to the pandaboard, but uses the twl6032 pmic and has a NAND memory from micron present.
The problem I'm facing is that I can't seem to boot directly from the nand memory chip. We've set the boot configuration pins to start with NAND boot, but it doesn't seem to work. On probing the CS and nand-busy lines we can see some activity happening, but don't understand what it means.
Any suggestions on how I could debug this?
If this NAND has bus-width = 16, then you need to tweak the board file with following changes. Below code is for AM335x platforms, you need similar for omap4 platforms
No, the NAND memory I'm using has a bus-width of 8.
How do you write on the nand the fist stage boot? Should be ecc check of the bootrom
