您好，麻烦你截一张完整的指令和信息输出图，这边看一下，可将截图发至我的邮箱（lzs@wch.cn）。或者你尝试将BOOT0接VCC重新上电下载看一下，看能否下载烧录。

这是我用OpenOCD+Telnet操作的情况: program指令运行时直接奔溃了 Open On-Chip Debugger > reset init JTAG tap: riscv.cpu tap/device found: 0x00000001 (mfg: 0x000 (), part: 0x0000, ver: 0x0) Bypassing JTAG setup events due to errors > flash erase_address 0x00000000 0x40000 device id = 0x263e7847 flash size = 256kbytes erased address 0x00000000 (length 262144) in 0.212762s (1203.222 KiB/s) > program C:/MRS_DATA/workspace/xx.bin 0x00000000 JTAG tap: riscv.cpu tap/device found: 0x00000001 (mfg: 0x000 (), part: 0x0000, ver: 0x0) Bypassing JTAG setup events due to errors ** Programming Started ** error writing to flash at address 0x00000000 at offset 0x00000000 embedded:startup.tcl:1136: Error: ** Programming Failed ** in procedure 'program' in procedure 'program_error' called at file "embedded:startup.tcl", line 1201 at file "embedded:startup.tcl", line 1136 failed read at 0x11, status=0 |

使用flash write_image指令一样的结果
> reset init JTAG tap: riscv.cpu tap/device found: 0x00000001 (mfg: 0x000 (), part: 0x0000, ver: 0x0) Bypassing JTAG setup events due to errors > flash erase_address 0x00000000 0x40000 device id = 0x263e7847 flash size = 256kbytes erased address 0x00000000 (length 262144) in 0.208332s (1228.808 KiB/s) > flash write_image xxx.bin 0x00000000 bin error writing to flash at address 0x00000000 at offset 0x00000000 failed read at 0x11, status=0 |

您好，建议你先用WCHISPTool工具通过串口方式解除读保护，重新下载程序试一下，注意不要勾选启用读保护。使用串口方式下载时：BOOT0接VCC，BOOT1接GND，使用的串口工具要注意防倒灌电。串口接串口1（PA9、PA10引脚）。
