I'm fooling with a cable modem that has a MIPS 4kc processor and cfi type flash chip from ST: M28W160CT. Flash configuration is as follows:
flash bank cfi 0x90000000 0X200000 2 2 $_TARGETNAME openocd-0.2.0 has no problem detecting the flash with "flash_probe" Some other differences I've noted between version 2 and the last two releases is in regards to endian ness. Dump_image in version 2 produces an output file where the ascii text (within the dump file) is in human readable order. The dumps with version 3 and 4 produce an image where the text is rotated or flipped. I've not been able to "load_image" with any version successfully or "flash write_image". It does, however erase the flash in version two. To solve my dilemma, I modified the source code to "HairyDairyMaid's" router debrick utility, which interestingly, some of the MIPS_4kc (openocd) source is based on. With the debrick utility, I was able to detect, read, erase, and write to the modem I was "tampering" with :). I WISH I could use Openocd for this task as I could use some of the additional TCL scripting features to automate testing and debugging. I've tried a few modifications by compairing the source from version 2 to 3 and have not had success. I'm reasonably certain my config file is not the issue, but I could be wrong.
