使用同样的代码和工程配置挂载合宙9.9元的开发板JTAG是可以的,环境使用的是Espressif-IDE 2.5
现在工程PCB使用的是ESP32-C3-MINI-U模组 观察硬件差异只有合宙9.9元的开发板的FLASH是外置的 ESP32-C3-MINI-U模组是片内FLASH 在工程中已经关闭了内存保护,但模组还是挂不上JTAG,日志如下: 大概能看出来是openocd对flash的操作有什么问题 Open On-Chip Debugger v0.11.0-esp32-20211220 (2021-12-20-15:43) Licensed under GNU GPL v2 For bug reports, read Info : only one transport option; autoselect 'jtag' Info : esp_usb_jtag: VID set to 0x303a and PID to 0x1001 Info : esp_usb_jtag: capabilities descriptor set to 0x2000 Warn : Transport "jtag" was already selected Flashing C:/Espressif/frameworks/esp-idf-v4.4/workspace/BMS76952_4S/build/partition_table/partition-table.bin at 0x8000 Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED Info : esp_usb_jtag: Device found.
