So to figure this out I started single stepping through u-boot with gdb. I get to line 186 in lowlevel_init.S. The line is str r1, [r0, #ESDCFG1_ROF]. This looks like a simple simple store instruction. Any thoughts as to why it stops there? thanks, Paul ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Re: [U-Boot] [PATCH 10/10] imx27lite: add support for imx27lite board from LogicPD
Hello Paul, I was trying to test out this patch, and I'm having some trouble. I did a git pull on the u-boot tree, and then I saved this patch to a text file. I was able to apply the patch just fine. The first thing that happend was make didn't like the Makefile, but I think it was just a space problem because after I edited the Makefile to match the entries around imx27lite_config it worked OK. Now when I run make it gives the error: make[1]: Leaving directory `/home/raid5/imx27env/u-boot/cpu/arm926ejs' make -C cpu/arm926ejs/mx27/ make: *** cpu/arm926ejs/mx27/: No such file or directory. Stop. make: *** [cpu/arm926ejs/mx27/libmx27.a] Error 2 How do I know what git version to use the patch against? If I were using git-am instead of just saving it to a file would that be different? Is there another patch I need? You need to apply other patches too (at least generic imx27 support and patch for serial console driver).

Re: [U-Boot] [PATCH 10/10] imx27lite: add support for imx27lite board from LogicPD
Hi I have now used the mxc_nand.c driver from patch 4 on a i.MX31 Litekit board and have some add some more input, see below. 2009/5/6 Magnus Lilja lilja.mag...@gmail.com: +/* + * NAND + */ +#define CONFIG_NAND_MXC +#define CONFIG_MXC_NAND_REGS_BASE 0xd800 It would be nice to have the REGS_BASE automatically set to whatever is appropriate for the SoC the code that is selected. I.e. it should be enough to specify CONFIG_MX31 in the board config file and then the NFC register base is handled automatically (and the equivalent for i.MX27). Other than that, the only change to make it work on i.MX31 Litekit was to disable the NAND bus width checking since that's currently i.MX27 specific code in mxc_nand.c so that would need some minor update for i.MX31.
