Part Number: AM62A7-Q1
Other Parts Discussed in Thread: SYSCONFIG, AM62A7
Hello, question has been locked.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1601185/am62a7-q1-am62a7-q1-using-wkup-uart0-as-main-uart0
i want to use WKUP-UART0 as MAIN-UART0 to output linux log in customer board base on k3-am62a7-sk.dts and linux is run normally, and now i want to change the WKUP-UART0 as MAIN-UART0 to output linux.
i make this change in uboot,but not work, no output
1.change dts: serial2 = &wkup_uart0;
2.change am62ax.env uart address: 0x2b300000(wkup_uart0 address in k3-am62a-wakeup.dtsi)
3.dev-data.c: add 114
I tried some of the suggestions provided, but wakeup0 still isn't outputting anything.(If using main0 produces output, it proves that the download link is working correctly.)
So, are any other changes needed?
