Netgear Stora install OpenWrt

Hi all! Maybe you can hrlp me.

I try install OpenWrt on my Stora. Use insruction from wiki https://openwrt.org/inbox/toh/netgear/netgear_stora Use files from Energoblock in this topic https://forum.openwrt.org/t/netgear-stora-ms-2000-openwrt-18-06-4/42104/10.

Uboot write is correct. But when I try boot uImage I have a error:

This u-boot has a limitation of 8MB for uImage. And the Stora uImage you tried to boot is 8.2MB. So they don't work together.

The maxsize 8MB is defined in u-boot mainline code. This u-boot is tracking mainline, with some OpenWRT patches. So in order to boot this Stora uImage you need a different u-boot version.

My release u-boot-2017.07 also uses CONFIG_SYS_BOOTM_LEN from mainline, so it will not work either.

OK. Thank tou for answer.

If I will build firmware from git https://git.openwrt.org/?p=openwrt/staging/wigyori.git;a=commit;h=94894e42116600d2d7b19cecebfcbaab4c04719d

do it work?

That should work (you should use that version because it is was patched specifically for OpenWRT). Change CONFIG_SYS_BOOTM_LEN to something like 10M or 12M.

Where can I change this variable? I find the patch file, but if I add the line

+#ifndef _CONFIG_NGMS2110_H
+#define _CONFIG_NGMS2110_H
+
+/*
+ * High Level Configuration Options (easy to change)
+ */
+#define CONFIG_MARVELL		1
+#define CONFIG_ARM926EJS	1	/* Basic Architecture */
+#define CONFIG_FEROCEON_88FR131	1	/* CPU Core subversion */
+#define CONFIG_KIRKWOOD		1	/* SOC Family Name */
+#define CONFIG_KW88F6281	1	/* SOC Name */
+#define CONFIG_MACH_NETGEAR_MS2110	/* Machine type */
+#define CONFIG_SKIP_LOWLEVEL_INIT	/* disable board lowlevel_init */
+#define CONFIG_SYS_BOOTM_LEN	(16 << 20) /* 16 MB */

With compile I have a error: unterminated #ifndef

Nevskiy,

That should not affect anything to cause such error.

I'd suggest you build the OpenWrt u-boot version as is (don't change anything). And then change the constant. Then rebuild.

In any case, even though they basically used my u-boot source as a base to built OpenWrt version, but they also have other OpenWrt-specific patches in that u-boot source. So if you see any error in building that u-boot, you should submit a bug report there and let the OpenWrt developers solve it.
