尊敬的 TI 专家：

参考项目：UCD3138FW-BIDI

https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/948886/ccs-ucd3138128-how-to-configure-cmd-file-for-64k-flash-size?tisearch=e2e-sitesearch&keymatch=UCD3138128%20Flash%20size%2064#

我在上面的 URL 中找到了有关此问题的相关信息、但尚未对其进行测试。

我还有几个问题需要确认、如下：

1.当我修改相应的 pflash 容量设置为64KB 时、函数调用 clear_integrity_word (0)后的参数是否应该进行相应调整？

或者是否应该修改"software_interrupt"案例12中的 zoiw_address 参数？请提供准确的操作说明。

    clear_integrity_word(0);        
}

int pmbus_write_rom_mode(void)
{
    rom_back_door();            
    return PMBUS_SUCCESS;           // Note: This line is never reached.  
}
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

void rom_back_door(void)
{
	// Call a SWI to clear the integrity words.
	clear_integrity_word(0);		
}


//==========================================================================================
// pmbus_write_rom_mode() 
//	Erases the program integrity word in FLASH, then waits for watchdog timer to reset the 
// CPU.  There is no return code or return from this function.  
//==========================================================================================
int pmbus_write_rom_mode(void)
{
	rom_back_door();			

	return PMBUS_SUCCESS;			// Note: This line is never reached.  
}

2.使用 UCD3XXX GUI 工具进行编程时是否有任何具体注意事项？ (例如：将闪存块复选框修改为"Block 0、1 64KB"？)

3.编程完成并重新上电后,从 ROM 切换到 pflash ,应该选择哪个选项?

谢谢。

您好 Parrish、

由于您只扩展块0的大小而不是选择块2、因此您可以将 clear_integrity_word ()的参数保留为"0"。
因此、您应该在 UCD3xxx 器件 GUI 中选择 Block 0、1 64KB 选项
在命令 ROM 执行其程序时、您可以在 GUI 中保持选择的默认块。

此致、

Jonathan Wong

尊敬的 Jonathan：

我在上一个链接中看到有人提到要修改校验和参数。
您能否告知应在何处进行修改？
我在下面粘贴的程序位置是否正确？

zoow_address = 0x7ff8；(更改为0xfff8？)

您好 Parrish、

Fusion Digital Power Studio 用户指南中的第5.2.1节介绍了如何配置 UCD3xxx 器件 GUI 以刷写多个块。

是的、是这样。您可以在 interrupt.c 文件中更改 zojw_address = 0xfff8。

尊敬的 Jonathan：

让我总结一下：

当修改.cmd 文件以将内存大小设置为64KB 时、案例12中的 zoj_address：if (arg1 = 0)也必须更新为 zoj_address = 0xfff8。

在刷写过程中、在 UCD3xxx 器件 GUI 中选择"Block 0、1 64KB"选项。
刷写后、要从 ROM 跳到 pflash、请选择默认 Block 选项。

是这样吗？

您好 Parrish、

是的、您的总结正确。

您是否要将存储器从4x 32kB 更改为2x 64kB 程序闪存？如果是、则可能需要注释掉 if (arg1 = 2)和 if (arg1 = 3)案例、并在 if (arg1 = 1)中更改 zoj_address = 1fff8。
