Unable to flash Thor Devkit

Hi,

Just to confirm: if you set uart0 back to status = “disabled”, does flashing/boot complete without the Unhandled Exception in EL3 error?

                uart0: serial@c5f0000 {
                       compatible = "arm,sbsa-uart","arm,pl011";
+                      status = "disabled";
-                      status = "okay";

Thanks

Hi @DavidDDD , yes currently i have removed this changes and the flashing works without error.

Hi,

uart0 must stay set to disabled, since it’s the debug console on the Thor devkit.
Does this setting meet your requirement?

Thanks

Hi @DavidDDD , this is my current pinmux on my carrier board and it will need uart0 as enabled.

Hi,

We dont support UART0 enabled as mentioned.
Please refer Making sure you're not a bot! to do other use case

Thanks

Hi @DavidDDD , as per the Design guide and Peripheral_Mappping, uart3 is mapped to uart0 and we have follow the same design in our custom board, any specific reason that uart0 can not be enabled?

Hi @DavidDDD , can you please guide on this

Hi,

As noted above, UART0 is reserved for the debug console and cannot be enabled. Please refer to the Peripheral Mapping documentation and use another UART interface to meet your requirements.

Thanks
