Hi Team,
We have design our custom board with IMX8MM SoC and below are the variations from EVK.
Peripheral Name | EVK | Custom board |
Console UART | UART2 | UART4 |
USB | 3.0 Type-C | 2.0 USB Type-B |
PMIC | PCA9450A | PCA9450A |
DDR | LPDDR4 - 2GB | DDR4 - 4GB |
eMMC | 16GB | 8GB |
we have verified all power rail voltages from PMIC and external power supply and all are Ok.
And there is no response either from USB and UART.
Queries.
1. Do we have any procedure to follow for first time flashing other than UUU.
2. any other way to debug the current state board. since there USB/UART is not working
3. Tried booting from SD Card, but didn't see any booting.
4. what would be the state of IMX8MM SoC after fabricating into the board.
Thanks,
Raghavendra
