CH32V303RC调试启动失败(error)

最近在调试时经常遇到启动调试时失败,无法联调,使用SWDTool经过擦除写入、掉电等一系列薛定谔般的操作后又有机会恢复调试连接。主要提示错误信息如下:

Error: error writing to flash at address 0x00000000 at offset 0x00030000

CH32V303RC芯片Flash容量480K,前192K为高速区。

不太清楚是什么原因引起,请问如何解决?

调试输出:

根据实际情况,项目使用的ld文件内存区域定义如下:

MEMORY

{

FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 192K

ROM_DATA1(rx) : ORIGIN = 0x00030000, LENGTH = 16K

ROM_DATA2(rx) : ORIGIN = 0x00034000, LENGTH = 32K

RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K

}


您好,您可以升级到MRS191,使用非零等待区的FLASH 可以按照下图配置一下。
