Hi, just tried to see if anyone in eCos MList could help me out. It was to do with the AEB-1 board. I Need the bin/hex of the AEB-1 RevC that supports SST flashes. The bin that comes in the cd only supports Atmel flashes and is version 0.01. Here is a description of my problem. Maybe something here is familiar to someone: ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ 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 you confirm this or can you send new boot.bin or even some suggestions/hints? 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. I attached the source code of the flasher, some terminal dumps of the boot communications. If you need anything else please advice. My AEB-1 SN is: 55075-002367 KPI-00041A Thanks in advance With best regards Carlos Sobrinho ######################################################################### # Boot # ######################################################################### Boot: ûá.« ARM Evaluation Board Boot Monitor 0.01 (19 APR 1998) Press ENTER within 2 seconds to stop autoboot Boot: modules Header Base Limit Data 04000004 04000000 040034a8 00000000 BootStrap 1.00 (14 Aug 1998) Boot: rommodules Header Base Limit 04000004 04000000 040034a8 BootStrap 1.00 (14 Aug 1998) 04003a74 04003800 04003bc0 Production_Test 1.00 (13 Aug 1998) 0400e7a4 04004000 0400e7ec Angel 1.03 (08 Mar 1998) ######################################################################### # Pluging Angel # ######################################################################### Boot: plugin angel Bad checksum 00030000 ^^^^^^^^^^^^^^^^^^^^^ Boot: Boot: rommodules Header Base Limit 04000004 04000000 040034a8 BootStrap 1.00 (14 Aug 1998) 04003a74 04003800 04003bc0 Production_Test 1.00 (13 Aug 1998) 0400e7a4 04004000 0400e7ec ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿe ######################################################################### # PrintEnv not working # ######################################################################### Boot: printenv Variable Value ======== ===== nocache Boot: setenv noautoboot ^^^^^^^^^^^^^^^^^^^^^^^ Boot: printenv Variable Value ======== ===== nocache ######################################################################### # Jtag Flash Programmer # ######################################################################### JTAG Flash Programmer v1.7 (Jan 31 2004) (c) Carlos Sobrinho <epilog@netvisao.pt> Serial Port init (38400 bps): [OK] Checking for IDCODE: [OK] `- Found SST29EE020 Flash Checking if flash is erased: [OK] Programming: 0x400000 -> 0x410000 ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ <snip> All OK !!!
