The SMC1 uses BRG7 and the SCC1 uses BRG1, should we have both BRGs configured in the .dts? ( BRG1 is configured). Device Tree and Chosen? Adding a chosen block and I end up off in the weeds. removing the chosen block and I die within cpm_uart_console_write chosen { linux,stdout-path = "/soc/cpm/serial@11a80"; }; In arch/boot/ep8248e, there is a call to: planetcore_set_stdout_path(table) is this why there is no chosen/stdout-path element in the device tree? Off to back out / replace the ep8248e + planetCore code to something more u-boot friendly. -Alan __log_buf when hung with ~ cpm_uart_console_write Using Embedded Planet EP8248E machine description.
