Hi! NXP Engineer

the schematic is refer to NXP development kit.

eMMC’s PS is from PCA9450C.

But, when use uuu in USB Serial Download mode, download image to eMMC, failed.

and, the  first line of uuu the screen is 100%, then the second line is flashed, and uuu is closed.

Only one  board (others is ok)has error as shown in the following capture.

PCA9450C votage is normal.

By the way，the total of two batches of PCBs were produced, with one PCB in each batch indicating this phenomenon.

Pls help to resolute this. Thanks.

Hi @www1519,

Thanks for the captures.

While flashing in the USB Serial Download mode, are there any logs on the UART debug console?

If yes, could you please share that?
