esp32-s3 的gpio无法设置JTAG接口

Postby liucheng » Thu Aug 18, 2022 7:29 am

根据文档(https://docs.espressif.com/projects/esp ... -jtag.html)描述:“烧录 JTAG_SEL_ENABLE eFuse 后,JTAG 接口的选择将由 strapping 管脚 GPIO3 来决定。ESP32-S3 复位时,如果该 strapping 管脚为低电平,JTAG 接口将使用 GPIO39-GPIO42,如果为高电平,USB_SERIAL_JTAG 将被用作 JTAG 接口。”

我需要执行:espefuse.py -p /dev/ttyUSB0 burn_efuse JTAG_SEL_ENAB
使能esp32-s3的管脚为JTAG接口失败

Code: Select all

#espefuse.py -p /dev/ttyUSB0  burn_efuse JTAG_SEL_ENABLE

请问原因是什么如何解决?

我已经验证过,编译环境是ok的,下载,命令,打印log都命令都可以正常执行
idf.py set-target esp32s3 (ok)
idf.py build (ok)
idf.py -p /dev/ttyUSB0 -b 460800 flash (ok)
idf.py -p /dev/ttyUSB0 monitor (ok)

文档有问题,对于 S3,应该是 STRAP_JTAG_SEL
JTAG_SEL_ENABLE 是针对 C3 的。

1 输入命令:STRAP_JTAG_SEL

Code: Select all

#espefuse.py -p /dev/ttyUSB0  burn_efuse STRAP_JTAG_SEL
/home/lc/esp/esp-idf/components/esptool_py/esptool/espsecure.py:18: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography and will be removed in a future release.
  from cryptography import exceptions
Connecting....
Detecting chip type... ESP32-S3
espefuse.py v3.3.2-dev

=== Run "burn_efuse" command ===
The efuses to burn:
  from BLOCK0
     - STRAP_JTAG_SEL

Burning efuses:

    - 'STRAP_JTAG_SEL' (Enable selection between usb_to_jtagor pad_to_jtag through GPIO3) 0b0 -> 0b1

Check all blocks for burn...
idx, BLOCK_NAME,          Conclusion
[00] BLOCK0               is not empty
	(written ): 0x0000000080000100000000000000d1f50000000000000000
	(to write): 0x000000000000000001000000000000000000000000000000
	(coding scheme = NONE)
. 
This is an irreversible operation!
Type 'BURN' (all capitals) to continue.

Aborting.
2 将GPIO3 接地,重启开发板
3 启动openOCD调试:

Code: Select all

lc@ubuntu:~$ 
lc@ubuntu:~$ sudo /usr/local/bin/openocd -c "adapter driver  cmsis-dap"

Info : SWCLK/TCK = 1 SWDIO/TMS = 1 TDI = 1 TDO = 1 nTRST = 0 nRESET = 1

我认为步骤1,2,应该已经调试到JTAG模式了,但是步骤3中还是报错“Error: CMSIS-DAP command CMD_DAP_SWJ_CLOCK failed.”
请问有解决思路吗?我感觉还是管脚设置不对呀。。。

1、esp openocd 应该还没有支持 CMSIS-DAP
2、为什么不直接用 builtin 的 jtag?
3、你要用 jtag 的话,要么整个 https://item.taobao.com/item.htm?spm=a1 ... 062944&mt=

麻烦解释一下,也利于其他遇到类似问题的开发者。另外,使用的是哪种 JTAG?
