OpenOCD: No progress with mpsse_flush( )

[GideonZ]

The mpsse implementation seems to be buggy. I cannot get this adapter to reliably work with OpenOCD. At times OpenOCD just hangs with the message "Haven't made progress in mpsse_flush()..."

This seems to happen more with OpenOCD 0.11.0-4, but I have also seen it happen with 0.10.0, which comes with Ubuntu (18.04 LTS).

For a way to reliably crash the device (admittedly a slightly different BL602...) see https://bbs.bouffalolab.com/d/118-restore-bl706-evb-mb-ability-to-upload-code/8 for a similar report.

I don't suspect this lands on Sipeed as much as it does Bouffalo and/or OpenOCD.

sipeed usb-jtag/ttl and sipeed rv-debugger lite can work, only sipeed rv-debugger plus have this issue.

Can anyone give me some advice?

[GideonZ]

I had the same issue. I also measured the JTAG signals with an oscilloscope. It was nonsense; TMS changing on both the rising and falling edges. I reported it to the seller and dumped it in the trash.

Been using an FTDI FT2232H since without issues.

So this is why I could not use this debugger in PlatformIO...

After re-flashing the debugger following the fixed instruction in https://github.com/sipeed/RV-Debugger-BL702/pull/15 it now works perfectly without such an error! The firmware initially uploaded on a new debugger might be somewhat broken.
