Using redboot with x/y modem

Hi.

I had sucess in downloading program by x/y modem of redboot.

Also, runing RAM Applicaiton program by redboot..

I have changed UART1 baudrate to 57600 by SOPC builder, and modified altera_avalon_uart_comm.c's altera_avalon_uart_diag_getc_timeout () functions in eCos driver.

~~~

typedef struct

{

cyg_uint8* port;

cyg_uint32 irq;

//Add by JYKoh

cyg_int32 msec_timeout;

//End

} altera_avalon_uart_chan;

~~~

cyg_bool altera_avalon_uart_diag_getc_timeout(void* __ch_data, cyg_uint8* ch)

{

int delay_count;

//Add By JYKoh

altera_avalon_uart_chan* chan = (altera_avalon_uart_chan*)__ch_data;

//End

cyg_bool res;

CYGARC_HAL_SAVE_GP();

//Chg by JYKoh

// delay_count = 10; // delay in .1 ms steps

delay_count = chan->msec_timeout * 10; // delay in .1 ms steps

//End

for(;;) {

res = altera_avalon_uart_diag_getc_nonblock(__ch_data, ch);

if (res || 0 == delay_count--)

break;

//Chg by JYKoh

// HAL_DELAY_US(10);

HAL_DELAY_US(100);

//End

}

CYGARC_HAL_RESTORE_GP();

return res;

}

~~

int altera_avalon_uart_diag_control(void *__ch_data, __comm_control_cmd_t __func, ...)

{

static int irq_state = 0;

altera_avalon_uart_chan* chan;

int ret = 0;

cyg_uint32 ctrl;

~~~

//Add by JYKoh

case __COMMCTL_SET_TIMEOUT:

{

va_list ap;

va_start(ap, __func);

ret = chan->msec_timeout;

chan->msec_timeout = va_arg(ap, cyg_uint32);

va_end(ap);

}

//End

default:

break;

}

CYGARC_HAL_RESTORE_GP();

return ret;

}

Hi Kohjy,

Thanks for posting that solution. Now that I have learned how to use u-boot I have decided that I like it so much that I will keep using it, it's really quite cool!
