OpenOCD config file for HiFive1 RevB

HiFive1 Rev B

Hi All

I am trying to connect to HiFive1 - Rev B using FreedomStudio-2019-08-2-win64 (SiFive Eclipse IDE for C/C++ Development, Version: 4.12.0.2019-08-2) but I cannot find the correct openocd.cfg file to use. Can someone point me to one that works please.

Hi,
you can find it here
But I don’t think the openocd version that comes with FreedomStudio support the hifive1-revB. you can try to get openocd from github and use it separately :slightly_smiling_face:

Hi KMA,

Thank you for the reply. I got it working with github version. The OpenOCD supplied with FreedomStudio could not work as you had predicted. That’s most likely why it did not have the the config file.

For me, the confirmation comes when the OpenOCD version shipped with FreedomStudio complains about “adapter driver jlink” command but the github version did not. The config file use “adapter driver jlink” , the OpenOCD shipped with FreedomStudio does not understand it, wanting the “interface” command. From playing with github’s version of OpenOCD, I found out that the “adapter” command is intended to replace the “interface” command.

Many thanks

Hi,

Is there a way to automate the download of the desired OpenOCD version through the platform settings?

No. First of all, OpenOCD does not do versioning. Secondly, to permit FreedomStudio to download any particular commit id comes with the implicit expectation that FreedomStudio tested that particular Commit ID. This has support implication for them.
