Hello again, everyone:
I am having trouble with the u-boot flash code on my target system. I am using the new 28F256K3 Intel chips on this target, instead of the 28F128J3A chips (which were on my development system).
U-Boot works with the 128J3A's but not with the 256K3's. I have tweaked the flash code so that it's correctly detecting the chips. And the u-boot runs out of these 256K3's when I program it into flash using JTAG. What does not work with the 256K3's is ERASING flash. And damned if I can figure out why. The u-boot code that is supposed to erase the flash just FLIES through in no time at all, without reporting any errors. But then when I try to write the flash-writing-code says "Error - flash not erased".
What do you think might be going on? How might I proceed to debug this? Does anyone out there have some test code that can erase the Intel Strata 28F256K3's?
Please advise - I am very lost and frustrated at the moment...
Thanks in advance, craig vanderborgh voxware incorporated
