OpenOCD支持CMSIS-DAP
DAP-LINK支持的晶元，我手上這款描述如下，應該JTAG協議的都支持
平臺
windows10 + ESP-IDF
ESP-WROOM-32E模組 + 燒錄底座
DAP-LINK
樂鑫OpenOCD
使用樂鑫官方的OpenOCD，結果無法識別CMSIS-DAP設備

官方OpenOCD
官方介面支持CMSIS-DAP，但是晶元並不支持ESP32
有cmsis-dap.cfg
沒有esp32的cfg
使用官方OpenOCD，配置文件使用樂鑫的，CMSIS-DAP可以正常識別，但確實不支持ESP32晶元

結論
-
樂鑫OpenOCD不支持CMSIS-DAP
-
官方OpenOCD支持CMSIS-DAP，但是不支持樂鑫的晶元
-
寄，還是下單了ESPLink
