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.

TsiChung,

thank you for the hint and warning.

I will have a look at it, but from U-Boot, accessing the flash seems to work perfectly (apart 
from writing being slower as with the BDM interface). It is the BDM interface I have problems 
with when writing to certain locations.

Regards,
Wolfgang
