According to the schematics the i.MX35 3-stack is without modifying it only able to boot in external boot mode, that is nand or nor flash. First step should be starting barebox as a second stage loader from the existing bootloader. For this the defconfig for the 3stack should be suitable. If you are using redboot you can use the following (replace 0x100000 with some valid sdram address): load -r -b 0x100000 barebox.bin run 0x100000 The same for u-Boot: tftp 0x80100000 barebox.bin go 0x80100000 If this works you should check if networking works: dhcp; tftp barebox.bin /dev/ram0 or, if you use the smc9117 on the debug board: ethact eth1; dhcp; tftp barebox.bin /dev/ram0 you can then flash barebox to either nand or nor flash: erase /dev/nor0.barebox; tftp barebox.bin /dev/nor0.barebox or: erase /dev/nand0.barebox.bb; tftp barebox.bin /dev/nand0.barebox.bb I suggest that you first try to flash barebox to the flash that does not contain your original bootloader (if you haven't got jtag) For getting a barebox suitable for starting from NAND you should enable CONFIG_NAND_IMX_BOOT in your config. The 3stack should be able to work in internal boot mode if TP41/42 on the personality board are adjusted. You also might want to apply the boot mode cleanup patch I just posted which makes it a bit clearer what boot modes are actually supported by barebox.

I never had a nand with 4k block size and I doubt it will work out of the box. I don't know if that's the reason barebox does not find no nand device at all though.

I'm also seeing problems with a 4k page size (+218 OOB) SLC NAND flash of Micron on i.MX25. Barebox does identify the flash chip, but can't read it correctly. I'm investigating the issue. So far I've found that the OOB area is read as 0x00s instead of 0xffs, even for good blocks. This makes Barebox to mark the whole flash as bad blocks. The Linux kernel, however, seems to work correctly with this flash when applying a small fix to use the correct(?) nand_ecclayout. baruch > > --------------------------------------- barebox output > > ------------------------------------------ > > barebox 2011.02.0 (Feb 25 2011 - 16:35:47) > > > > Board: Freescale MX35 3Stack > > No NAND device found!!! > > cfi_probe: cfi_flash base: 0xa0000000 size: 0x04000000 > > mc13892-i2c@mc13892-i2c0: PMIC ID: 0x000045d0 [Rev: 2.0a] > > smc911x: no smc911x found on 0xb6000000 (byte_test=0x00f000f0) > > imx-ipu-fb@imx-ipu-fb0: i.MX Framebuffer driver > > mc13892-i2c@mc13892-i2c0: revision: 0x45d0 > > i.MX35 PDK CPU board version 1. > > Malloc space: 0x86f00000 -> 0x87f00000 (size 16 MB) > > Stack space : 0x86ef8000 -> 0x86f00000 (size 32 kB) > > Open /dev/env0 No such file or directory > > no valid environment found on /dev/env0.

Further investigation shows that the Linux kernel doesn't read (or write) the OOB area correctly. This is not a problem if all you do is program the barebox image into the NAND flash. However, since the kernel uses the OOB area to identify the BBT (bad block table), the BBT gets corrupted. When that happens, the mxc_nand .probe fails at nand_scan_tail(). I suspect that the nandv2_hw_eccoob_largepage is wrong for 4K+218B. I'm still investigating. baruch > Am 28.02.2011 09:19, schrieb Baruch Siach: > > Hi Sascha, Thomas, > > > > On Mon, Feb 28, 2011 at 10:09:23AM +0200, Baruch Siach wrote: > > > >> On Mon, Feb 28, 2011 at 08:40:53AM +0100, Sascha Hauer wrote: > >> > >>> On Fri, Feb 25, 2011 at 05:08:10PM +0100, Thomas Mayer wrote: > >>> > >>>> thanks, I will try that. > >>>> Today I got our real hardware.
