Error: double-check your JTAG setup #107

Open CarlFK opened 5 years ago

CarlFK commented 5 years ago

(Error: double-check stood out as maybe a clue to why f--lash-image needs 3 runs ((it seems to always be 3 on my test rig)))

I power cycle the opsis, run this 3 times,

hdmi2usb-mode-switch -v --by-type opsis --flash-image image-gateware+bios+firmware.v0.0.4-489-geaab51f.opsis.hdmi2usb.lm32.bin

and diffed the output, noticed some 'Error' lines in the first 2 runs: run 1:

Warn : Unexpected idcode after end of chain: 85 0xfffffa20
Error: double-check your JTAG setup (interface, speed, ...)
