It seems to accept ejtag: jtag> initbus ejtag jtag> But then: jtag> detectflash 0 ejtag.c(177) EJADDRESS, EJDATA or EJCONTROL register not found ... dev ID=0000 man ID=0000 ejtag.c(177) EJADDRESS, EJDATA or EJCONTROL register not found ... amd_detect: mid 0, did 0 Flash not found! But there's something that puzzles me; sometimes, couldn't find the way to reproduce it, the chip enters a state where: jtag> detect IR length: 4 Chain length: 1 Device Id: 00000111100100100110010001110111 (0x0000000007926477) Unknown manufacturer! chain.c(149) Part 0 without active instruction chain.c(200) Part 0 without active instruction chain.c(149) Part 0 without active instruction which is a completely different chip which was not detected in the other state; can you interpret this? Then, after a while, it comes back to the state I reported in the first place. > if there is, you'll then have to > figure out what information it needs (signals, instructions, etc...). then > you'll have to define at least those in a data file (see the many examples in > the data/ directory). if there is no bus driver, then you'll probably have to > figure out one (writing a new one from scratch or based on an existing one). > > then you should be able to tell urjtag to use that data file for that part in > the chain, initialize the required bus, and then start poking the flash. > So, would you say it is accepting ejtag and, if so, what is the minimum set of data I need; in the meanwhile, I'll try to figure that out of the examples as you pointed.
