Description:

In the STM8S For IAR Embedded WorkBench

I consulted AN2659 - AIP write the BootLoader, In the STM8S003F3,STM8S903K3 and 005 can be normal operation. But in the STM8S207K6 First:

The sample program:

/****************************************************************************************/ // When shake hands with PC successfully. CLK->CKDIVR = 0x00; // CLK Config FLASH->PUKR = 0x56; // UNLOCK FLASH->PUKR = 0xAE; FLASH->DUKR = 0xAE; FLASH->DUKR = 0x56; RoutinesInRAM = 1; // Just a Flag for(unsigned char i = 0;i < 248 ;i++) // Clear Flah for Program my Protect2 { Write_Flah_Block_Data((0x8400 + 128*i),(unsigned char *)&Receive_Data_Buffer[0],128); //

Dead Here

}

// Mean I can not Program in the ram

// Program In the RAM void Write_Flah_Block_Data(unsigned short Start_Address,unsigned char *Ptr,unsigned char Length)@''FLASH_CODE'' { FLASH->CR2 |= 0X01; FLASH->NCR2 &= (unsigned char)~0X01; for( unsigned char i = 0; i < Length ;i++) { *(( PointerAttr unsigned char*) (unsigned short)Start_Address + i) = *Ptr; Ptr++; } } /*****************************************************************************************************************/ Second:

The ICF File

: // ///////////////////////////////////////////////////////////////// define memory with size = 16M; define region TinyData = [from 0x00 to 0xFF]; define region NearData = [from 0x0000 to 0x17FF]; define region Eeprom = [from 0x4000 to 0x43FF]; define region BootROM = [from 0x6000 to 0x67FF]; define region NearFuncCode = [from 0x8000 to 0xFFFF]; define region FarFuncCode = [from 0x8000 to 0xFFFF]; define region HugeFuncCode = [from 0x8000 to 0xFFFF]; ///////////////////////////////////////////////////////////////// define block CSTACK with size = _CSTACK_SIZE {}; define block HEAP with size = _HEAP_SIZE {}; define block INTVEC with size = 0x80 { ro section .intvec }; initialize by copy { rw, ro section .tiny.rodata, section FLASH_CODE}; do not initialize { section .vregs }; do not initialize { section .*.noinit }; // Placement place at start of TinyData { rw section .vregs }; place in TinyData { rw section .tiny.* }; place at end of NearData { block CSTACK }; place in NearData { ro section FLASH_CODE, block HEAP, rw }; // includes rw section .near.* place at start of NearFuncCode { block INTVEC }; place in NearFuncCode { ro section .far.data_init, ro section .huge.data_init, ro }; // includes ro section .near_func.* place in FarFuncCode { ro section .far.*, ro section .far_func.* }; place in HugeFuncCode { ro section .huge.*, ro section .huge_func.* }; place in Eeprom { section .eeprom.* };
