Today I received a new RT1020 board and I have test RT1020 and RT1050 boards with MCUXpresso 10.1.0 and 10.2.0, Multilink PE and Jlink programmers (after cut the wires 1 and 2 of JTAG to avoid damage again the board), and also tested with DAP Link CMSIS-DAP driver by USB.
This is a headache, Jlink is the only one that works with RT1020 and RT1050, but only with 10.1.0 MCUXpresso. Multilink also works with RT1050 but only with version 10.1.0 MCUXpresso. MCUXpresso 10.2.0 fails with all the programmers, USB driver and both boards.
These are my tests:
RT1050 + MCUxpresso 10.1.0 + DAP LINK CMSISI-DAP Driver --> FAIL
RT1050 + MCUxpresso 10.2.0 + DAP LINK CMSISI-DAP Driver --> FAIL
RT1020 + MCUxpresso 10.1.0 + DAP LINK CMSISI-DAP Driver --> FAIL
RT1020 + MCUxpresso 10.2.0 + DAP LINK CMSISI-DAP Driver --> FAIL
RT1050 + MCUxpresso 10.1.0 + Multilink PE programmer --> OK
RT1050 + MCUxpresso 10.2.0 + Multilink PE programmer --> FAIL
RT1020 + MCUxpresso 10.1.0 + Multilink PE programmer --> FAIL
RT1020 + MCUxpresso 10.2.0 + Multilink PE programmer --> FAIL
RT1050 + MCUxpresso 10.1.0 + Jlink programmer --> OK
RT1050 + MCUxpresso 10.2.0 + Jlink programmer --> FAIL
RT1020 + MCUxpresso 10.1.0 + Jlink programmer --> OK
RT1020 + MCUxpresso 10.2.0 + Jlink programmer --> FAIL
Therefore, currently, only Jlink works with RT1020 and RT1050 with MCUXpresso 10.1.0, and RT1050 with Multilink and MCUxpresso 10.1.0. I have deleted and reinstalled MCUXpresso and drivers several times, I work with Windows 7 64 bits.
I sent this problem to NXP, I hope they help me solve the problem or some new release of MCUXpresso.
