Hi,
We have created a custom board with the i.MX8QM. Currently, we are evaluating it using an evaluation board (i.MX8QM MEK) until the custom board is ready. We are using BSP version LF6.6.3_1.0.0, so we are using SCFW version 1.15.0.
On the custom board, Linux controls UART_2. The pin configuration is as follows:
UART0_RTS_B - UART2_RX
UART0_CTS_B - UART2_TX
Therefore, we moved the resource allocated to M4_1 (Partition 4) to U-Boot/Linux (Partition 6) in SCFW. The changes in SCFW are as follows:

};
When using flash.bin (flash_linux_m4) which includes the modified scfw_tcm.bin, the kernel fails to boot with an error during startup.
I am attaching the kernel boot log from that time.
Do you have any ideas on what could be causing this?
