Hi guys,
I implemented the Dominic suggestion to ignore the iMX31 IR error:
http://forum.sparkfun.com/viewtopic.php?t=7841&postdays=0&postorder=asc&start=45&sid=45354d14976fd68c1fa088693f66ed7f
I commented the lines 1475, 1476, 1487 and 1488 of src/jtag/jtag.c:
free(cbuf);
//free(ir_test);
//return ERROR_JTAG_INIT_FAILED;
}
chain_pos += device->ir_length;
device = device->next;
}
if (buf_get_u32(ir_test, chain_pos, 2) != 0x3)
{
char *cbuf = buf_to_str(ir_test, total_ir_length, 16);
LOG_ERROR("Error validating JTAG scan chain, IR
mismatch, scan returned 0x%s", cbuf);
free(cbuf);
//free(ir_test);
//return ERROR_JTAG_INIT_FAILED;
}
OpenOCD detected iMX31 processor, but it doesn't opened the telnet
neither gdb port.
This is the openocd output:

Can someone please give me some suggestion about how to solve this problem?
