However, I shouldn't need to, in that the old programmer does work.

I cannot change the target boot code, as it is already deployed. In the case of the target device, I did not include the main loop, which contains the getData call, the decode call, the program call (all three of which seem to work) and the sendCmd call, shown above, that does not (with my programmer).

I have tried to include the minimum amount of code necessary to understand the problem. SpiWrite(AT86RF230_CMD_FW) // write to FIFO frame bufferįor(i=0, length = (txFrame - 1) i> 5) & 0x7 setup 1281 interrupt, only use PINE5, not interrupt

The programmer sends the first packet, which appears to acknowledged. When my programmer begins its ill-fated quest, all starts well. (As a historical note, I have ATZB-24-B0 based programmer that works for both, but I do not have access to the source code.) As of now, it works if the target device is also a ATmega256RFR2, but does not work if the target device is a ATZB-24-B0 module. I have been writing the code for a wireless programmer.
