Hi there,
Iam using Keil uVision3(MDK 3.11) with GNU compiler for my LPC2368 based project.

Iam seeing the following error (undefined reference to '__udivsi3') and warnings( missing braces around initializer) :
Build target 'MCB2300'
assembling Startup.s...
compiling LPC2000_CAN_Driver.c...
src/LPC2000_CAN_Driver.c(72): warning: missing braces around initializer
src/LPC2000_CAN_Driver.c(72): warning: (near initialization for 'CAN_Send_Data[0].DataField')

src/LPC2000_CAN_SYS.c(225): error: undefined reference to '__udivsi3'
collect2: ld returned 1 exit status
Target not created

The error message points to the code line
"temp_uart0 = (Fpclk/16)/Baudrate; " in the following source code :

void uart0_config(UInt32 Baudrate,UART0MODE U0_config)
{
UInt32 temp_uart0;
U0LCR = 0x80; // DLAB=1, Can use U0DLM, U0DLL
temp_uart0 = (Fpclk/16)/Baudrate;

U0DLM = temp_uart0>>8;
U0DLL = temp_uart0&0xFF;

temp_uart0 = U0_config.Datalength - 5;
if( U0_config.Stopbit == 2 ) temp_uart0 |= 0x04;

if( U0_config.Paritybit != 0 )
{
U0_config.Paritybit = U0_config.Paritybit - 1;
temp_uart0 |= 0x08;
}
temp_uart0 |= U0_config.Paritybit<<4;
U0LCR = temp_uart0;
U0FCR = 0x07;
U0IER = IER_RBR | IER_RLS;
}
The warning points to the following code:

lpc2000CANdriver_TXObj_t CAN_Send_Data[] {{0x00080000,0x00000001,0x12345678,0x12345678},
{0x00080000,0x00000002,0x12345678,0x12345678},
{0x00080000,0x00000347,0x12345678,0x12345678},
{0x00080000,0x000003F1,0x1643F6E5,0xD4C3B2A1}};

I have observed that, in the Linker settings if the
option "Donot use Standard system libraries" is not selected then the error is not reported by the compiler. But, the UART doesnot work.

I have tried out the same program using Real View Compiler and it works fine.

Kindly give me your suggestions.

Thanks in Advance,

Hi,
Also, I would like to add the following observations

Iam not using printf. Iam using the following routine to print the output on the PC's hyperterminal.
Iam seeing some junk values appear on the hyperterminal.

Print_4bits_to_Screen( (Temp_Data_Output[i] & 0x000000F0)>>4 );
UInt32 Print_4bits_to_Screen( UInt32 Value_Hex_4bits)
{
switch(Value_Hex_4bits)
{
case 0:
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9: U0THR = Value_Hex_4bits + 48; // print "0 - 9"
break;
case 10:
case 11:
case 12:
case 13:
case 14:
case 15: U0THR = Value_Hex_4bits + 55; // print "A - F"
break;

case 32:
case 44:
case 45: U0THR = Value_Hex_4bits;
break;
default:
break;
}
while( (U0LSR & 0x20) == 0 );
return(0);
}

So, please I would like to know whether this program is wrong.
Is it that one has to use putchar function for GNU compiler.

Regards,
Chetan

Looks like the baud rate is set wrong on the LPC CPU

Dear Jean-Jacques,

Yes you are correct. Thank You.
I have set right the baud rate in the startup file.
Now it's working fine.

Ok

But did you find out about the problem with the linker undefined
reference '__udivsi3' as I have the same problem

Try searching the forum for "udivsi3" and you should get some answers.

Brendan Start a New Thread

Hi Jean,

Sorry, forgot to mention that. Yes, the error "__udivsi3" got debugged
.
Under the Linker Options , uncheck the option "Donot use Standard System
Libraries".

But, iam still unable to debug the warnings.

Cheers,
Chetan

Hi All

I still have a problem to resolve "__udivsi3"

I use Eclipse and GNU tool chain

Did you search the forum for "udivsi3" as I suggested? Start a New Thread

hello again,

stupid me, used 30 mhz instead of 20.
so, you calculation is right, mine is wrong.

sorry for the fuzz...
