Re: esp32s3 在windows上通过USB烧写失败

我在一台装了win10的笔记本上烧写成功了,会不会是台式机USB驱动有问题?

【已解决】esp32s3 在windows上通过USB烧写失败

IDF v4.4.4
ESP32S3
menuconfig相关设置是‘CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG’
然后通过type-c口进行烧写,在ubuntu上没有问题,但是在win10上不行。在相应的usb口上倒是可以monitor,但是没有办法flash,一直timeout错误。
请问怎么解决?

lsusb 看下有哪些 USB 设备?
问题解决了,用usb cdc烧写的时候端口是 `/dev/ttyACM*`,而不是常用的`/dev/ttyUSB*`

【已解决】使用esp32-s3的USB Serial/JTAG口连接linux时,找不到设备

一直以来我使用uart口进行烧写,在linux和windows上都正常,这两天尝试了用USB Serial/JTAG口,我用的是官方开发板进行连接。
其中,不需要任何改动就可以在windows上进行烧写(甚至不需要设置CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG),但是连接linux后,一直找不到相应的/dev/ttyUSB*设备,我也尝试了下载`60-openocd.rules`文件放到了`/etc/udev/rules.d`然后重启终端也找不到,可能是什么原因呢?我只进行烧写,不需要jtag调试。

Re: ESP32-S3 hardware timer interrupt doesn't work stable

Hi,is it possible that a timer ISR operations are pre-empted by WiFi interrupts? I have faced an identical problem: when wifi is working, especially transmitting data package(about 5kB/package) through mqtt, the timer isr sometimes misses. Could you try starting a task pinned to core 1 and initializ...

how to reduce interrupt latency?

greetings sdk: IDF V4.4, hd:ESP32-S3 when a pulse is detected by one io, an spi transaction will be triggered. Through oscillometer I found the interval between the pulse and spi cs signal was as much as 100~200 us, while this thread says the interrupt latency can be reduced to about 2 us. Is there ...

Re: wifi connection issue

I think I found the reason: esp32 cannot get the right gw IP. When connected wifi, the gw ip is always set to "192.168.1.167", then esp32 cannot connect to network. Sometimes it get the right gw ip "192.168.1.1", then the network is fine.
How can I fix this problem?

wifi connection issue

esp32s2 idf v432 hi my esp32 can connect to wifi without any problem. But, most times it cannot connect to network. So it cannot set network time and cannot connect to my mqtt server. I noticed one thing: after connected to wifi, when "aid" is 3, esp32 can connect to netowrk, when "aid" is 1 or 2, i...
