Did you copy the parts that setup the pinmuxing in s_init for NOR?
This bit ?
#ifdef CONFIG_NOR_BOOT asm("stmfd sp!, {r2 - r4}"); asm("movw r4, #0x8A4"); asm("movw r3, #0x44E1"); asm("orr r4, r4, r3, lsl #16"); asm("mov r2, #9"); asm("mov r3, #8"); asm("gpmc_mux: str r2, [r4], #4"); asm("subs r3, r3, #1"); asm("bne gpmc_mux"); asm("ldmfd sp!, {r2 - r4}"); #endif
Yes ... :-)
Below is my entire s_init() routine.
One question ... the SPL code has:-
... gd = &gdata; ...
But there seems to be no similar assignment when in NOR boot mode. I'm no expert in the internal workings of u-boot, so I thought I'd check, just in case !?!
I just noticed you mentioning "gd" here and wanted to point you to a patch that fixed a gd-related boot issue for me on OMAP3:
[U-Boot] [PATCH 1/3] arm: spl: Fix SPL booting for OMAP3
(sorry, I can't find a link to this patch right now and I'm in a hurry)
Not sure if this has something to do with your problem (I don't have the time to dig into this mail thread today as I'm leaving right now).
Cheers, Stefan
