I submitted the following bug report on Sourceforge --- ------- msp430-jtag MSP430 parallel JTAG programmer Version: 2.0 processor MSP430F169 OS Linux (FC2)
On a functioning system msp430-jtag failed to download. Subsequent attempts to erase the flash memory produced the error: An error occoured: Could not write target memory Using msp430-gdbproxy/gdb(DDD) I was able to erase the flash memory. msp430-jtag now functions properly as it did prior to the memory write error. ------- I am not sure if the bug report was accepted. After hitting the submit there was no message stating the report was accepted or even received. When I hit the browse button on the bug report screen my report does not show up.
