Need bin of AEB-1 Boot (Arm Evaluation Board 1 / LH77790B CPU)

Hi I'm having a few problems with my AEB-1. Sometime ago I accidentally deleted my boot but managed to get it back using a jtag program. Now I can even see the flash contents using arm-elf-gdb/x 0x40000. I programmed all the 256 kB of flash memory but now I'm having a few problems regarding flashwrite/flasherase/setenv/etc

I already tried with SDP Enabled and SDP Disabled

I already tried both bin's that the cd offers. Revc1.bin (CS =

0x3D45 ) and At29c020.bin (CS = N/A)

I already tried putting the bin to program directly in the flash but plugin fails with bad checksum

I even tried disabling the cache but with no success...

When ever I try to write to the flash using something like flashwrite, setenv it simply doesn't work.

My best guess is that the bin's in the cd are either wrong (Rev B) or don't support SST29EE020 flash. Can anyone confirm this or can anyone send new boot.bin or even some suggestions/hints?

I attached the source code of the flasher, some terminal dumps of the boot communications. If you need anything else please advice.

What I need is some version later than 0.01 "ARM Evaluation Board Boot Monitor 0.01 (19 APR 1998)"

Thanks in advance With best regards Carlos Sobrinho

PS1:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If anyone want's the JTAG code I'll post it. Currently it supports serial feedback and $1 USD building a wiggler. Just connect it to pppc_arm_rgdb using jtag cable and run my program...

PS2:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I have just found out using a small C program to dump the content of the flash at address 0x4018000 that the boot isn't working properly regarding sectors size. I see 256 bytes erased and only 128 bytes written. It seems that Revc1.bin and At29c020.bin don't support SST flash with 128 bytes/sector. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
