imx93 uart1 to uart2

bora — Thu, 03 Apr 2025 05:55:01 GMT

I am trying to change the debug interface on my custom i.MX93 board. By default, it uses UART1, but I want to switch it to UART2. I have read related topics and followed the suggested steps, but it still doesn’t work.

What could be the possible reasons for this issue? Any help would be appreciated!

std-out = &lpuart2

changed BASE Adress

#define IMX_LPUART_BASE U(0x44390000)

changed imx93_evk.c :

static iomux_v3_cfg_t const uart_pads[] = {
MX93_PAD_UART2_RXD__LPUART2_RX | MUX_PAD_CTRL(UART_PAD_CTRL),
MX93_PAD_UART2_TXD__LPUART2_TX | MUX_PAD_CTRL(UART_PAD_CTRL),
};

Hello,

The code init_uart_clk in arch/arm/mach-imx/imx9/native/clock.c only contain UART1, you need add UART2.
