Hi,

we are using keil evaluation board for str912fw44.We are not able to work with examples which use stlib.only ex blinky without lib we are able to do.Is there any problem or we are doing any mistake.Please guide me.

Hello,

if you want to use the Stlib example (witch are writen for IAR compiler) you should use the ''like IAR'' startup file These two file initialise chip like IAR startup does and then call the KEIL C Stdlib start code. ps this only work with keil V3.xx

hi,

here we are using MCBSTR9 Evaluation Board. for this board only one example has given. it is working. the path for this program is: ARM/RV30/BOARDS/KEIL/BLINKY. program is: #include void delay(u32); int main (void) { SCU->GPIOOUT[7] = 0x5555; /* P7.0..7 output - mode 1 */ GPIO7->DDR = 0xFF; /* P7.0..7 Outputs (LED Data) */ while (1) { /* Loop forever */ GPIO7->DR[0x3FC] = 0xF0; /* Turn on LED */ delay(0x0FFF); GPIO7->DR[0x3FC] = 0x0F; /* Turn on LED */ delay(0x0FFF); } } void delay(u32 i) { u8 j; while(i-->0) for(j=0;j<=100;j++); } The path for another program :ARM/RV30/BOARDS/ST/BLINKY ,with some modifications according to my board, is not working. i don't know why it is not working in my board(MCBSTR9 Evaluation Board). the modified code which is not working in my board is: #include ''91x_lib.h'' GPIO_InitTypeDef GPIO_InitStructure; u32 var; void SCU_Configuration(void); static void Delay(u32 nCount); int main() { #ifdef DEBUG debug(); #endif SCU_Configuration(); GPIO_StructInit(&GPIO_InitStructure); /* GPIO Configuration ------------------------------------*/ GPIO_DeInit(GPIO7); GPIO_InitStructure.GPIO_Direction = GPIO_PinOutput; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_All; GPIO_InitStructure.GPIO_Type = GPIO_Type_PushPull ; GPIO_Init (GPIO7, &GPIO_InitStructure); while(1) { GPIO7->DR[0x3FC] = 0xFF; Delay(0x0FF); GPIO7->DR[0x3FC] = 0x00; GPIO_WriteBit(GPIO7, GPIO_Pin_0, Bit_RESET); GPIO_WriteBit(GPIO7, GPIO_Pin_1, Bit_RESET); GPIO_WriteBit(GPIO7, GPIO_Pin_2, Bit_RESET); GPIO_WriteBit(GPIO7, GPIO_Pin_3, Bit_RESET); Delay(0x0FF); } } void SCU_Configuration(void) { SCU_APBPeriphClockConfig(__GPIO7 ,ENABLE); } static void Delay(u32 nCount) { u32 j = 0; for(j = nCount; j != 0; j--); } to work this program in my board (MCBSTR9) what i have to do? Thanks in advance regards raj.

hi raj,

have you check if the __GPIO7 is defined in the right way? the label is in the SCU_Configuration(). the correct label there could be GPIO7, the other one seem to be a CUP generated label.

Posted on May 17, 2011 at 09:33''this only work with keil V3.xx'' Hello, we have used 91x_vect.s,91x_init.s along with STR91x.s as start up code.But still we are facing the same problem. let me know anybody is there who works on the same board(MCBSTR9). can u please help us. regards anuradha.

Hai stevejamal,

ya it is the right way to define like __GPIO7. The program which i have given is working program for STR910 EVALUATION BOARD which is supplied by ST. but we are using MCBSTR9 Evaluation board which is supplied by KEIL. here for this board just i have changed the GPIO9 to GPIO7. Rest is same.

hi anuradha,

try to add to the GPIO_Initstrcture GPIO_InitStructure.GPIO_Alternate=GPIO_OutputAlt1; I compiled your code with iar and without this field the gpio doesn't work. If you see in the blinky example there is SCU->GPIOOUT[7] = 0x5555; /* P7.0..7 output - mode 1 */ Ste

Hai Steve,

thanks for u'r reply. i have modified my code according u'r sugession. but no use. i think there should be need to modify the start up code, what do u say? here we are using KEIL-REALVIEW compiler and MCBSTR9 Evaluation board. could u please send the working code for me. thanks & regards raj.

Hai Steve,

now it is working. thank u. raj........
