What are the first bytes after the 0x55 that the GRMON sends to a system. I have a ColdFire V1 with several peripherals connected using the GPL GRIP IP but can’t get my system to come up in GRMON.
I was able to capture this communication after seeing 0x55 sent initially. So, what is the response I should see from the system. Rx is what grmon is sending after the 0x55 bytes and Tx is what should be coming from the system. What should I be getting from the system as a sequence of bytes after it sends that string 0x80 0xFF 0xFF 0xFF 0xF0 to the system.
Writing the short COM# device name only works for single digit COM devices in Windows. For devices greater or equal to 10 you need to use the full device path, for example \.\com11
I got it working with Linux WSL but will try that out. One thing is sometimes it takes multiple tries for the grmon to open. Sometimes, I get multiple msgs of UART timeouts. Eventually after 10 attempts it fails. Then hitting reset a few times, usually gets it connected. Is that because it failed to negotiate the communications or maybe something not resetting correctly in my design.
