LPC55S69 flash freezes #715

Open juhhov opened 5 years ago

juhhov commented 5 years ago

The freeze occurs very often. Flash never continues when at this state. Version in use: ddf36148a959fe27598c6d244b1039cd7b888293

Hi, @flit did you have time to look into this issue?

flit commented 5 years ago

My apologies, I have not. But I've been using the LPC55S69 lately and for some reason have not come across this issue.

What is the state of the device prior to flashing? Does it still fail like this if you run 'pyocd erase --chip' before this test?

juhhov commented 5 years ago

This usually reproduces when another flash is started right after previous has finished.

juhhov commented 5 years ago

Retested with v0.22.0. The freeze is still there. Can not succesfully run 'pyocd erase --chip'. It always fails with below traceback. This sometimes happens also when flashing.

@flit - any chance of getting some runtime for this?

JanneKiiskila commented 4 years ago

@mmahadevan108 @maclobdell - can we get some runtime for this? This is severely hampering the usage of this board in the CI/automated testing setup.
