I can't say much about the protocol though it is described in the controller's manual, something about xmodem is stated, but I'm not much into that. Summarized sam-ba talks to an application stored in the internal ROM of the controller. As you can see, at least some data is written and read, because i could detect which processor the device has attached. But the problem arises if a binary is downloaded into sram of the controller. Oh, and if I retry to start sam-ba after it got stuck first, if stop at the line "-I- target(handle) : file5" where, I guess, it writes/reads to the device first in that session. > > Alexander, does the 2.6.35-rc6 kernel also have this problem? Yes, I'm currently running 2.6.35-rc6 and the problem still occurs.
