Summary: u-boot does not boot on BF526 EZKIT from NOR flash

Details:

 

I built a u-boot.ldr from latest trunk for bf526-ezkit, and programmed it in the NOR flash on the board through jtag. The u-boot didn't boot, I saw nothing on minicom.

 

Follow-ups

please verify that the binary posted to the u-boot project boots and verify that

you are doing a cold boot (aka hardware reset or power cycle)

 

software reset will not work

u-boot-bf526-ezkit-para.ldr downloaded from u-boot release page does not boot

here.

then verify your bootmode and other such jumpers.  you should also test booting

over SPI and UART as both of those work for me.

 

i think Bryan had things working ?  so you can compare your board to his ...

I failed to make the BF526-EZKIT work on my side, because I didn't program the

ldr to the board. So Jie is trying to help to fix here.

 

Actually, I am debugging the BF527-EZKIT board with BF526 processor bug.

the jumper/switch settings should be pretty much the same as the bf527-ezkit.

so make sure all the important pieces are the same.

Hi Mike,

 

Could you send me a photo of your bf526 ezkit, such that I can compare the

jumpers?

 

Thanks,

Jie

you can find documentation here:

Yeah, the jumper was not removed from JP2 (loopback). It looks well after it's

removed. Not a bug. Close.

Yes, the board is ok for both U-BOOT and kernel.

But it still failed on BF527-EZKIT board with BF526 installed.

Even same kernel and same uboot.

Robin said to just throw away that board.  focus on the real bf526-ezkit.  there

wont be anymore bf527-ezkit's with a bf526 on them ... that was a limited run to

help verify the silicon worked.

FYI:

BF526 CCLK max is 400MHz.

>But it still failed on BF527-EZKIT board with BF526 installed.

 

Even when setting CCLK = 400MHz ...

 

I found the same thing.
