Hello we are using IMX RT-1052 on custom board. We use QSPI flash and PE Micro Universal Multilink as debug probe. We can program and debug program on cpu. We use boot option as internal boot (GPIO _AD_B0_04 DNP and GPIO_AD_B0_05 connected). All programs runs on ram ( we did not download code to flash, link application to ram option selected in linker). After random number of debug sessions, we lost connection with target processor although we did not changed any setting. We have this problem regularly.
Our solution for this problem is: Change boot option to serial downloader (GPIO _AD_B0_04 connected and GPIO_AD_B0_05 DNP), power up then change boot option to internal boot. After this process we can communicate with IMX RT-1052.
We did not have permanent solution for this problem and we don't know why this problem occurs.
