Reassigned pin power group

faiz — Fri, 06 Sep 2019 16:20:21 GMT

Hello,

On our board, we have UART power group (NVCC_UART) connected to 1.8V and SPI power group (NVCC_ECSPI) connect to 3.3V.

We want to reassign ECSPI1_SCLK (D6) and ECSPI1_MOSI (B7) to UART3.RX and UART3.TX. Would the voltage group be 3.3V or 1.8V?

Thanks,
Faiz

Hello,

i.MX8Mm pins ECSPI1_SCLK (D6) and ECSPI1_MOSI (B7) belong to NVCC_ECSPI power group,

therefore the mentioned UART signal will be under 3.3V.

Use the i.MX Pins tool.

Have a great day,

Yuri
