Dear Lauri Hintsala, > Hello, > > I'm trying to compile latest U-Boot to mx28evk (rev D) with NAND > support. U-Boot boots up but NAND chip is not detected and DMA read > error is popped up. MX28 EVK has no NAND, right? Otherwise, check if you have APBH DMA enabled in your include/configs/mx28evk.h btw Fabio, can you please ping me on jabber? > Here is console output: > > U-Boot 2012.04-rc2-dirty (Apr 17 2012 - 10:58:50) > > Freescale i.MX28 family at 454 MHz > DRAM: 128 MiB > NAND: MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: Error sending command > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: Error sending command > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > MXS NAND: DMA read error (-110) > No NAND device found!!! > 0 MiB > > > I did following changes to mainline code.

Yes, they seem to be disabled: #define CONFIG_SYS_ICACHE_OFF #define CONFIG_SYS_DCACHE_OFF I'm using latest U-Boot and default mx28evk.h config: http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/mx28evk.h;h=02f3366ed263ff66fe3b9b2089ec95ef461a92c0;hb=HEAD I have added only NAND related lines I sent in first message.

Lauri, as much as I'd love to help you, MX28EVK is Fabio's board. So let's see what he has to say ;-) > > BR, > Lauri Best regards, Marek Vasut

The issue was caused by the missing iomuxing. I'll do the patch... Thank you for your friendly and fast responses. BR, Lauri
