Hello,
i tried to upgrade the STM32 firmware on my reTerminal as mentioned in the wiki.
The board revision is v1.3 and the firmware before flashing was 1.0
openOCD always fails with a timeout while writing but the connection seems to be OK
since it is able to get some infos over the SWD link.
After some hours of trying i put the Terminal back together to check if everything is still working and now the Display stays blank. (reTerminal DTO is enabled)
I already tried the following:
- Try flashing with/without Display/TP/Light connected
- different cables and connections (jumper wires, pogo-pins, test-leads, IC-Clips)
- clean and reconnect Display/TP/Light
- copy openOCD files/dirs for target, interface, cpu into working directory
- relative and absolute path for firmware file
I’m pretty inexperienced regarding JTAG/SWD and clueless what else to do.
Can someone help me out here and give me some hints how to proceed?
Thanks
