Hi,
I have a HiFive1 board and I have been using it for two months now. I am using openocd to program the board, and more specifically I am using a branch at fa8d7adf33986302100313a791418423a7d4c758 commit.
For some reason now, I am unable to reprogram the board. I am using the following commands:
make OPENOCD_DEBUG_LEVEL=3 PROGRAM=hello TARGET=sifive-hifive1 CONFIGURATION=debug software
make OPENOCD_DEBUG_LEVEL=3 PROGRAM=hello TARGET=sifive-hifive1 CONFIGURATION=debug upload
The compilation logs show that I cannot get some device info, and I get a timeout in the end as shown below:

My question is the following:
What is the dtmcontrol_scan(): DTMCONTROL: 0x10000 -> 0x1550 command trying to read? Maybe the specific output from the functioning board will help:

I am suspecting that have “fried/broke” something on the board but I am trying to understand what.
Thanks!
