My CW Husky recently became unresponsive / unreachable. I attempted to reflash, but the firmware update never completed. I also tried shorting SJ1 to erase the flash, but that doesn’t seem to have any effect. All 4 LEDs (2 red, green, and blue) are solid when powered.
Is there anything else that can be done to recover the device?
Thanks
What is the output of:
import chipwhisperer as cw
cw.program_sam_firmware(hardware_type='cwhusky')
I don’t recall the exact message, but I believe I’ve managed to get it back to working. Running “make program” from the CW Husky git repo following the instructions here did the trick.
Great! For future reference (and for others who find this post), there is no need to rebuild the firmware; its compiled binary is included in the chipwhisperer installation. Instructions for programming firmware, for all the situations we could think of (including a seemingly bricked scope) are here.
