[U-Boot-Users] U-boot for MCF5329

[Liew Tsi Chung-r5aahp]

Wolfgang,

	Check your NOR flash model make sure your flash algorithm able to support -B and -T version, u-boot CFI driver able to configure both model. Also, unlock the Read only bit in u-boot (prot off bank #) before you use the BDM. Some flash will lock itself after reset, if I recall correctly, M5329EVB Intel flash JS28F160C3 is one of them.

IMPORTANT NOTE: Intel flash has a feature that will lock certain block permanently. Make sure not writing to this bit. Otherwise, you have to replace the whole flash.

Regards,
TsiChung

I am running on my custom board. The flash is working there, too - the only problem is that there are some places in flash where it seems I can only write with U-Boot, not from the BDM interface. I have no idea why, but this is why I currently need running from RAM here to flash the image...

With the workaround mentioned in the last mail running from RAM works, but depending on configuration, the risk is that CPU and/or bus clock are not at the correct values. I can live with that, but it would be nice to solve it.
 
Sorry I can´t help you with the CS2 problem!

With the MCF5329 port running on MCF5373L, I also do have another funny problem:
I cannot boot my linux image.
The image is decompressed (taking around 3 times longer than with my old U-Boot port, BTW), and when starting the kernel, there is no reaction any more. Again, no idea yet, but I will let you know when I find out.

Wolfgang
