Hi William,
I tried hard coding the irq and i/o address of my serial card in
serialio.h and did a make clean, make and make modules_install, ran depmod
-a again to be sure and even rebooted, but the synth is still not being
detected.
Is there anything else I need to change in the source to hard code my
serial port?
Here is what I changed in serialio.h:
#ifndef SERIAL_PORT_DFNS
#define SERIAL_PORT_DFNS \
/* UART CLK PORT IRQ FLAGS */ \
{ 0, BASE_BAUD, 0xCC, 16, STD_COM_FLAGS}, \
/* { 0, BASE_BAUD, 0x3F8, 4, STD_COM_FLAGS }, /* ttyS0 */ \
*/
{ 0, BASE_BAUD, 0x2F8, 3, STD_COM_FLAGS }, /* ttyS1 */ \
{ 0, BASE_BAUD, 0x3E8, 4, STD_COM_FLAGS }, /* ttyS2 */ \
{ 0, BASE_BAUD, 0x2E8, 3, STD_COM4_FLAGS }, /* ttyS3 */
#endif
and here is what setserial shows for ttyS0:
/dev/ttyS0, Line 0, UART: 16950/954, Port: 0xcc00, IRQ: 16
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
Thanks,
Trevor
