The following link chronicles the same behavior but the answers don't seem to apply. http://lists.linuxppc.org/linuxppc-embedded/200203/msg00238.html This thread from the ppcboot-users mailing is relevant as well. http://www.geocrawler.com/mail/thread.php3?subject=%5BPpcboot-users%5D+Linux+console+messages+garbled&list=4205 The problem is that I'm missing every other character on the console port which looks like this (captured using Tera Term Pro's log function): >> ## Transferring control to Linux (at address 00000000) ... >> tlmmr 6B sn 4Bfrhs al a 070)iu eso .. ro@y)(c eso .532001 peees/rno2001) 8 u a 71:12 D 03nnd oapgs 06oe0:49 ae.oe1:0pgs >> zn() ae.enlcmadln:ro=dvrmr >> Wrig eltm lc em tc I'm using u-boot-0.3.0 which has CONFIG_CONS_ON_SCC defined as opposed to CONFIG_CONS_ON_SMC. I presume the 'make MPC8266ADS_config' set that up. I modified arch/ppc/8260_io/uart.c so that SCC1 corresponds with CONFIG_SERIAL_CONSOLE_PORT. However, this did not fix the problem. my rs_table looks like this: >> #define CONFIG_SERIAL_CONSOLE_PORT 0 >> >> . >> . >> . >> >> static struct serial_state rs_table[] = { >> { 0, 0, PROFF_SCC1, SIU_INT_SCC1, 0, SCC_NUM_BASE + 0}, /* SCC1 ttyS 2 */ >> { 0, 0, PROFF_SCC2, SIU_INT_SCC2, 0, SCC_NUM_BASE + 1}, /* SCC2 ttyS 3 */ >> { 0, 0, PROFF_SCC3, SIU_INT_SCC3, 0, SCC_NUM_BASE + 2}, /* SCC3 ttyS 4 */ >> { 0, 0, PROFF_SCC4, SIU_INT_SCC4, 0, SCC_NUM_BASE + 3}, /* SCC4 ttyS 5 */ Can anyone shed some light on this issue?
