juhhov commented 4 years ago

Flash MIMXRT1050-EVKB board constantly fails. There seems to be two type of errors occurring. Daplink details.txt and full traces are attached.

Error number one: pyocd.probe.pydapaccess.dap_access_api.DAPAccessIntf.TransferError: No ACK received Error number two: pyocd.core.exceptions.DebugError: No cores were discovered!

$ pyocd --version
0.24.1

Hi All,

I believe https://github.com/mbedmicro/pyOCD/pull/838 + https://github.com/mbedmicro/pyOCD/pull/845 should have fixed the pyocd flash command issue.

While the pyocd erase command still have "No ACK received" errors.

Just FYI.

Thanks.

Sounds like this case could be closed a new one should be raised for the --erase, instead.

After few flash rounds the board goes to "No cores were discovered!" state and has to be restored with dip switch altering and erase. This blocks CI usage.

Steps:

  1. pyocd flash -Oconnect_mode=under-reset -vvv -u 02270b0341114e45005d300ac207003692d1000097969900 -t mimxrt1050_hyperflash printer_MIMXRT1050_EVK.hex
  2. pyocd flash -Oconnect_mode=under-reset -vvv -u 02270b0341114e45005d300ac207003692d1000097969900 -t mimxrt1050_hyperflash payload_MIMXRT1050_EVK.hex
  3. pyocd flash -Oconnect_mode=under-reset -vvv -u 02270b0341114e45005d300ac207003692d1000097969900 -t mimxrt1050_hyperflash payload_null_MIMXRT1050_EVK.hex

Ok, then this definitely cannot be closed. This is a blocker issue, @mmahadevan108 @maclobdell - can we get some runtime, please? Test automation simply will not work this kind of behaviour.

Created #861 and #862. I'll close this.
