Hi All,<br><br>I am trying to boot Linux-2.6.38 on custom build MPC8250 board with all SCC's and SMC's configured as UART's. <br>As device tree file for 8250 is not available I referred mpc8272ads file and created the one attached.<br>
<br>I could able to use SMC1 or SCC1 as serial port in u-boot.<br><br>I could get Linux serial console on SCC1 but not on SMC1. Port configuration has been set correctly in Linux.<br><br>For some reasons Linux serial console on SCC requires user to press <ENTER> key to enter the console and also to mount root file system.<br>
<br>One more strange problem is, console won't come up if I pass boot argument console=ttyCPM0,115200 through u-boot. <br>I am passing stdout-path through device tree file for serial console<br><br>I am not sure where I am doing mistake. <br>
I set the cpm-muram-data to <0 4000>. Rest of the DPRAM is reserved.<br><br>I request you to go through device tree file and suggest a solution. I need SMC1 to work as serial console.<br><br>Thanks,<br>Suresh<br>
