Hi everyone I'm trying to use an AVR ICE mkII to program a jtag chain with two atmega 16 in it, and when i read the flash from the second AVR in the chain it is read back as shifted one step left. The does not seem to run at all, which makes me think it is written wrong. However, when writing the flash with AVR studio and its built in flashing program it works fine.
The data shift looks like I'm trying to write it too fast or that the instruction chain length is off. This is my first real experience with JTAG chains so sorry if i've jumped to the wrong conclusions. I have tried to mimic the settings that work in AVR Studio but not succeeded, i can't figure out what if anything the -i and -B flags does to the JTAG clock. My question is simply what could cause this sort of behavior? // Caj _______________________________________________ AVR-chat mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/avr-chat
