Hi, I have mpc8xx where I would like the following configuration: - SCC1 as system console (works fine) - SMC1-2 as UART (doesn\'t work)
I use linux 2.6.16.20 with backward patch from linux-2.6.19.2 for SMCs. My only problem is that even I can see cpm_uart registered for IRQ 20 (for SMC1) I never get interrupt even I do e.g. \"echo 123 > /dev/ttyCPM\". here is a short extract from /proc/interrupts: 20: 0 CPM Edge cpm_uart <--SMC1 21: 7546 CPM Edge SPI 46: 20 CPM Edge cpm_uart <-- SCC1 (console) here is a short extract from /proc/tty/driver/ttyCPM: serinfo:1.0 driver revision: 0: uart:CPM UART mmio:0xFFF00A80 irq:20 tx:14 rx:0 RTS|CTS|DTR|DSR|CD 1: uart:CPM UART mmio:0xFFF00A90 irq:19 tx:0 rx:0 CTS|DSR|CD 2: uart:CPM UART mmio:0xFFF00A00 irq:46 tx:3038 rx:46 RTS|CTS|DTR|DSR|CD Can anybody help me to get SMCs working? thnx, Ladislav. __________ http://chat.post.sk - zachatujte si s priatelmi na IRC.POST.SK _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
