Hi all, I had the same problem under linux (Debian woody):
msp430-gdbproxy --debug msp430 debug: msp430: msp430_open() error: msp430: Could not find device (or device not supported) (4) And I found the reason in the HIL.c file. In two functions: ReadTDI and ReadTDO there is written the following line: ret = ioctl(fd, PPRSTATUS, &ret); ^^^| This will overwrite the data from the MSP430... chip. Without the lefthand operand it works better: ioctl(fd, PPRSTATUS, &ret); Have fun ... Andre
