the NAND boot does not work yet. I was not able to make it work with a SPL only because the BootROM only reads the first page. The Lantiq UGW U-Boot uses a very small pre-loader which loads another pre-loader and fits in the first page. Thus we need to convert to SPL/TPL support from mainline U-Boot. But I hadn't enough time yet to work on it. > > --- a/arch/mips/cpu/mips32/arx100/config.mk 2015-01-27 12:33:32.000000000 > +0100 > +++ b/arch/mips/cpu/mips32/arx100/config.mk 2015-01-27 18:07:37.000000000 > +0100 > @@ -27,4 +27,9 @@ ALL-y += $(obj)u-boot.ltq.norspl > ALL-$(CONFIG_SPL_LZO_SUPPORT) += $(obj)u-boot.ltq.lzo.norspl > ALL-$(CONFIG_SPL_LZMA_SUPPORT) += $(obj)u-boot.ltq.lzma.norspl > endif > +ifdef CONFIG_SYS_BOOT_NANDSPL > +ALL-y += $(obj)u-boot.ltq.nandspl > +ALL-$(CONFIG_SPL_LZO_SUPPORT) += $(obj)u-boot.ltq.lzo.nandspl > +ALL-$(CONFIG_SPL_LZMA_SUPPORT) += $(obj)u-boot.ltq.lzma.nandspl > +endif > endif > > > Then the ebu configuration word needs to be set in the nandspl > image, as it is for norspl.

The XWAY_EBU_BOOTCFG is only used for parallel NOR to setup various command timings and delays. > > --- a/arch/mips/include/asm/arch-arx100/config.h 2015-01-27 > 18:12:32.000000000 +0100 > +++ b/arch/mips/include/asm/arch-arx100/config.h 2015-01-27 > 18:13:02.000000000 +0100 > @@ -174,6 +174,10 @@ > #define CONFIG_XWAY_SWAP_BYTES > #endif > > +#if defined(CONFIG_SYS_BOOT_NAND) || defined(CONFIG_SYS_BOOT_NANDSPL) > +#define CONFIG_SYS_XWAY_EBU_BOOTCFG 0x688C688C > +#endif > + > #define CONFIG_SYS_MONITOR_BASE CONFIG_SYS_TEXT_BASE > > #endif /* __ARX100_CONFIG_H__ */ > > Finally the ltq-boot-image tool adds a couple of download header to the > final image which I don't think should be there. > > Daniel, does all the above make sense? > > That said, even after making those changes my nandspl images still > don't work. > > Ben > > > > -- - Daniel _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
