DAPLINK FIRMWARE UPDATION ON EVKB

anjalikkrishna — Tue, 10 Jul 2018 05:30:18 GMT

Hi ,

I tried to update the DAPLINK FIRMWARE of the EVKB board by following the steps as given in the attached document.

I was trying to update the EVKB board with the on-board QSPI support firmware . But even after hardware changes QSPI was not working. So I planned to revert the old state of the board by flashing the default firmware which I got from the same site . OpenSDA Serial and Debug Adapter|NXP

I connected the board to my PC through opensda and tried to debug using MCUXpresso. But "Wire ACK Wait on DAP Access " error is occuring. Usually I ll go for a Hyperflash erase when this error occurs . But when I try to erase the following error appears

Executing flash operation 'Erase' (Erase flash) - Tue Jul 10 10:41:18 IST 2018

Hi.

Please refer

IMXRT1050-EVKB - Error debugging using CMSIS-DAP

From FEEDBACK: erasing the Hyperflash memory solves this problem. The hyperflash can be erased using the 'GUI Flash toool' in MCUXpresso

Have a great day,
Jennie Zhang
