Hi,
I want to change u-boot debug console from UART1 to UART4 for imx8qm. What changes do I do ?
I applied the below changes in u-boot but it didnt work.
Hi @HAKANAYDN
Refer this to compile scfw firmware on Ubuntu, not yocto.
Then find and replace scfw_tcm.bin in Yocto.
Hi,
Where do I fix inside source code of scfw in order to change from uart1 to uart4 for console ? After I apply it, do I need to do something inside kernel, uboot and dts files ? After I compiled scfw file, how can I combine u-boot.bin both of them ? How can I flash ?
You should refer the knowledge base :https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/System-Controller-Firmware-101-Resource-...
after I apply it, do I need to do something inside kernel, uboot and dts files ?
-->Yes, you need configure uboot and kernel serial index in dts.
After I compiled scfw file, how can I combine u-boot.bin both of them ? How can I flash ?
-->Please refer 4.5.13 How to build imx-boot image by using imx-mkimage in this guide.
