Hi
We made a customized i.mx8mn board with ddr4.
Now we have some issues with the DDR training and stress test.
The uart debug port can be recognized by our computer. However, the USB OTG port seems is not recognized by our computer.
And when doing USB download, we got the following error:
Please check if the correct target is selected and set to the serial download mode.
We are using PCA9450 as our PMIC. As my understanding, the USB serial download will always succeed regardless of the setting of our pmic register value. Am I right here?
Solved! Go to Solution.
