I'm having trouble getting the serial console to work on an EP8343M board when using U-Boot 1.2.0 to start Linux 2.6.20.1. I'm using arch powerpc and platform MPC834x_SYS (which is perhaps wishful thinking, as my board is different, although it should at least have the same serial port configuration).
The symptoms are exactly the same as those in http://ozlabs.org/pipermail/linuxppc-embedded/2006-September/024457.html: the console stops working after the call to console_init(). The suggested solution was to ensure that U-Boot is setting timebase-frequency, bus-frequency and clock-frequency and passing those properties to the kernel, and this does indeed seem to be happening in my case. I've attached the output from U-Boot (including a dump of the flat device tree), as well as my kernel config and U-Boot board settings. Any help would be appreciated. --Ed -------------- next part -------------- A non-text attachment was scrubbed...
