Apps rild & socket issue on Samsung S3C6410

[vikingmsi]

Hi,
The content of my logcat is as below. Sometimes, I get a line "D/AT (1956) AT> AT", and then didn't see any log sent from the D/AT; and sometimes I can see the log until AT> CTREG+1. Anyway, I never saw the /dev/socket/rild is alive.

Can anyone help this?

Hi,
Sometimes I can only send 1 AT command, and sometimes 2 or 3. Somehow the thread "readerloop" terminates or disappears...

I modified two files:
1. reference-ril.c, in mainloop
=====================================
.....
fd = open(s_device_path, O_RDWR);
//Viking debug if ( fd >= 0 && !memcmp( s_device_path, "/dev/ttyS", 9 ) ) {
if ( fd >= 0 && !memcmp( s_device_path, "/dev/s3c2410_serial1", 20 ) ) { //Viking debug
/* disable echo on serial ports */
struct termios ios;
tcgetattr( fd, &ios );
bzero(&ios, sizeof(ios)); /*Viking debug*/
//Viking debug ios.c_lflag = 0; /* disable ECHO, ICANON, etc... */
/*Viking debug - Start*/
cfsetispeed(&ios,B115200);
cfsetospeed(&ios,B115200);
ios.c_cflag|=(CS8|CREAD);
ios.c_iflag|=IGNPAR;
tcflush(fd,TCIFLUSH);
/*Viking debug - End*/
tcsetattr( fd, TCSANOW, &ios );
......
2. atchannel.c
=========================================
while (p_eol == NULL) {
if (0 == MAX_AT_RESPONSE - (p_read - s_ATBuffer)) {
LOGD("Viking >>> ---------- readline 5 -----------"); //Viking debug
LOGE("ERROR: Input line exceeded buffer\n");
/* ditch buffer and start over again */
s_ATBufferCur = s_ATBuffer;
*s_ATBufferCur = '\0';
p_read = s_ATBuffer;
}
/*Viking debug - Start*/
tv.tv_sec = 1; /* 1 second*/
tv.tv_usec = 0; /*0 micro second*/
pos = 0;
count = 0;
FD_ZERO(&rfds);
FD_SET(s_fd, &rfds);
retval = select(s_fd+1, &rfds, NULL, NULL, &tv); //<= Sometimes the systems stops here
/*Viking debug - End*/
do {
count = read(s_fd, p_read,
MAX_AT_RESPONSE - (p_read - s_ATBuffer));
} while (count < 0 && errno == EINTR);
if (count > 0) {
AT_DUMP( "<< ", p_read, count );
s_readCount += count;
