efuse 烧写协议

我们想在efuse中烧写设备SN码,并查看相关块的写入内容,写上位机的工程师认为espefuse.exe插件用起来太麻烦,想自己实现,请问这个烧写的通讯协议能否提供下?

This can be accomplished via cmake. Have a look at the COMPONENTS bullets here: https://docs.espressif.com/projects/esp ... -variables
Thanks,I will try to check it out.

Re: How Do I Disable the ESP-IDF Component That Is Not Used in a Project?

the files generated by these useless components occupy a lot of flash space I suggest to check if this is actually the case by running idf.py size-components . Thanks for your response. You're right, but there are still a few in the stats, and I'm not sure if the project really needs those componen...

How Do I Disable the ESP-IDF Component That Is Not Used in a Project?

hello,I have some problems when I work with esp-idf V5.2.1. Some functions before the compilation of the project are confirmed to be not turned on in menuconfig, but after the project is compiled, the corresponding .a file is generated in the build/esp-idf folder, and the corresponding functions are...

Re: 新手求助 如何从vscode进入menuconfig

首先,确认vscode 已经安装了 esp-idf的扩展插件,安装好后vscode 左侧边栏出现esp-idf explorer图标,打开工程,(如果没有就再点几下左侧esp-idf explorer的图标)会在底部看到一个小齿轮的图标,点击那个小齿轮就能进入。

Re: ESP32-S3 正常运行中重启 rst:0x7 (TG0WDT_SYS_RST),boot:0x9 (SPI_FAST_FLASH_BOOT)

更新下信息: 复现问题:芯片使用ESP32-s3r2,外接8MB flash/DIO。 1、一个按键使用了GPIO35,当GPIO初始化为输入并内部上拉后,连续多次按连接GPIO35的按键,会导致出现TG0WDT_SYS_RST的情况,而且很频繁,不初始化GPIO35,未复现到TG0WDT_SYS_RST该问题。 怀疑是IDF启用了GPIO35的相关功能,导致GPIO35配置为输入后,功能冲突。4.4和5.0、5.2版本IDF环境下都编译测试过,都有TG0WDT_SYS_RST该问题。 同一批次线路板测试都会出现该问题,后边又改进部分硬件信号问题,但GPIO35相关按键电路都未改动,重新做了一...

ESP32S3R2 BLE设置发送功率与实际发送功率差别大,且实际发送功率不稳定

如题,使用ESP-IDF4.4.6版本 ,BLE发送功率设置9dbm, 实际输出最大发送功率在0dbm左右,但每次断电重新上电,测到的发送功率只有-1dbm,-2dbm,与设置的发送功率差异大。

对于设置发送功率与实际发送功率差异大的原因有哪些?BLE发送功率与设置的发送功率在多少区间内算是合格的?

Re: ESP32-S3R2 如何配置开启PSRAM? 我开启PSRAM后 报错:找不到PSRAM芯片

重新配置后 没有问题了 ,但是出现了另外一个问题: 使用串口的时候,调用时uart_driver_install函数,uart_alloc_driver_obj()未申请到内存,查看底层发现heap_caps_calloc()未申请到内存,实际查看,空闲内存还有124K之多。请问还需要修改其他配置吗?
