Can we use the MSCALE DDR Test Tool without access to the serial interface?
We have a i.MX8M prototype with serial access only at UART3. Is it possible to change the MSCALE DDR Test Tool to use the UART3?
With best regards
Unfortunately this is not possible since the ROM code of the i.MX always use the same UART when the device was not able to boot, an enter in serial download mode, so in our case, we design the tool in order to use this Serial Port. And there is no option to modify and select another.
a colleague found a way to change the uart interface, documented here: https://community.nxp.com/docs/DOC-340179
we tried it with our prototype and it works
