Well, now that I've got IRQs requestable, I'm back to battling SCC1 / SCC4 initialization,
I've verified the iop structures, and things look set-up correctly. /* SCC1 */ {2, 14, CPM_PIN_INPUT | CPM_PIN_PRIMARY}, {2, 15, CPM_PIN_INPUT | CPM_PIN_PRIMARY}, {3, 29, CPM_PIN_OUTPUT | CPM_PIN_PRIMARY}, {3, 30, CPM_PIN_OUTPUT | CPM_PIN_SECONDARY}, {3, 31, CPM_PIN_INPUT | CPM_PIN_PRIMARY}, /* SCC4 */ {3, 21, CPM_PIN_OUTPUT | CPM_PIN_PRIMARY}, {3, 22, CPM_PIN_INPUT | CPM_PIN_PRIMARY}, I've also verified that upon first use (echo "test" > /dev/ttyCPM[12] the brgs are configured) SCC1 cpm_uart_startup:417 CPM uart[1]:startup on IRQ: 40 - request returned 0 cpm_uart_startup:432 CPM uart[1] is scc CPM uart[1]:set_termios cpm_setbrg [cpm2_common.c:106] e00119f0:00010140 CPM uart[1]:shutdown SCC4 cpm_uart_startup:417 CPM uart[2]:startup on IRQ: 43 - request returned 0 cpm_uart_startup:432 CPM uart[2] is scc CPM uart[2]:set_termios cpm_setbrg [cpm2_common.c:106] e00119fc:00010140 CPM uart[2]:shutdown CPM uart[2]:initbd However, SCC1 continues to get locked. Am I missing something in the PRAM areas?
