大家好，我想把官方给的TMS570L04的CAN 的bootloader 移植到 TMS570LS0232上，在执行CAN_COMMAND_DOWNLOAD命令过程中，程序卡在BLInternalFlashStartAddrCheck(g_ulTransferAddress, g_ulTransferSize)里出不来。该函数已经被我改了，如下：
uint32_t BLInternalFlashStartAddrCheck(uint32_t ulAddr, uint32_t ulImgSize)
{
uint32_t count=0, i;
uint32_t ulWholeFlashSize;
uint8_t ucStatus;
//
// Determine the size of the flash available on the part in use.
//
ulWholeFlashSize = (uint32_t)flash_sector[NUMBEROFSECTORS-1].start + flash_sector[NUMBEROFSECTORS-1].length; /* 128K */
/* The start address must be at the begining of the sector */
for (i = 0; i < NUMBEROFSECTORS-1; i++){
if (ulAddr == (uint32_t)(flash_sector[i].start))
{
count++;
}
}
if (count == 0){
#ifdef DEBUG_MSG_L3
//UART_putString(UART, "\r Application Address should be aligned with flash sector start address!\r");
// ucStatus = data_start_address_error;
// PacketWrite(CAN_PORT, CAN_COMMAND_ACK, &ucStatus, 1);
#endif
return(0);
}
//
// Is the address we were passed a valid start address? We allow:
//
// 1. Address 0 if configured to update the boot loader.
// 2. The start of the reserved block if parameter space is reserved (to
// allow a download of the parameter block contents).
// 3. The application start address specified in bl_config.h.
//
// The function fails if the address is not one of these, if the image
// size is larger than the available space or if the address is not word
// aligned.
//
if((
#ifdef ENABLE_BL_UPDATE
(ulAddr != 0) &&
#endif
(ulAddr != APP_START_ADDRESS)) ||
((ulAddr + ulImgSize) > ulWholeFlashSize) ||
((ulAddr & 3) != 0))
{
#ifdef DEBUG_MSG_L3
// UART_putString(UART, "\r Flash address and size check failed!\r");
#endif
return(0);
}
else
{
#ifdef DEBUG_MSG_L3
// UART_putString(UART, "\r Flash address and size check passed!\r");
// ucStatus = data_address_size_error;
// PacketWrite(CAN_PORT, CAN_COMMAND_ACK, &ucStatus, 1);
#endif
return(1);
}
}
我移植的过程如下：
第一步：添加头文件路径和添加F021的库，如下图：
库添加后，出现了警告，警告如下图：
请问这是不是我的库添加错了，我换了 F021_API_CortexR4_LE.lib 库，发现错误还是存在。
第二步：改CMD
TMS570LS0232的FLASH如下图：
我写的CMD如下：
MEMORY

麻烦大家指教一下，非常感谢！
