Hello, everyone !
I have TQM5200S module and development board.
It runs factory UBoot and latest DENX's linuxppc_2_4_devel kernel.
I want to configure all TQM5200S's onboard PSC's as UART's.
TQM5200S's onboard PSC's are connected to custom board
that makes all electrical things as my hardware engineer says...
So changed $HOME/linuxppc_2_4_devel/arch/ppc/platforms/tqm5200.h
the following way:
#ifdef CONFIG_PS2MULT
#define RS_TABLE_SIZE 4
#else
#if defined(CONFIG_SPI_EVAL) || defined(CONFIG_TB5200)
#define RS_TABLE_SIZE 2
#elif defined(CONFIG_CAM5200)
#define RS_TABLE_SIZE 6
#else
#define RS_TABLE_SIZE 3
#endif
#endif
changed to
#ifdef CONFIG_PS2MULT
#define RS_TABLE_SIZE 4
#else
#if defined(CONFIG_SPI_EVAL) || defined(CONFIG_TB5200)
#define RS_TABLE_SIZE 2
#elif defined(CONFIG_CAM5200)
#define RS_TABLE_SIZE 6
#else
#define RS_TABLE_SIZE 6
#endif
#endif
and
#else /* default */
#define SERIAL_PORT_DFNS \
STD_PSC_OP(1) \
STD_PSC_OP(2) \
STD_PSC_OP(3)
#endif
changed to
#else /* default */
#define SERIAL_PORT_DFNS \
STD_PSC_OP(1) \
STD_PSC_OP(2) \
STD_PSC_OP(3) \
STD_PSC_OP(4) \
STD_PSC_OP(5) \
STD_PSC_OP(6)
#endif
After rebuilding the kernel, dmesg says:
...
ttyS0 on PSC1
ttyS1 on PSC2
ttyS2 on PSC3
ttyS3 on PSC4
ttyS4 on PSC5
ttyS5 on PSC6
...
But when i do "echo 1 > /dev/ttyS4" i receive nothing at the other end.
The questions are:
Is it possible to reconfigure all PSC's as UART's ?
Should i change something in UBoot or everything i did was wrong ?
P.S. Sorry for my poor english and newbie questions :-)
