[SOLVED] Question about reset RC and boot network

@ESP_Sprite thanks

About the 10pF capacitor, I saw it on this schematic https://files.seeedstudio.com/wiki/XIAO ... C3-SCH.pdf
I think you are right. It must be there to avoid parasitic bounces on the button.

Question about reset RC and boot network

Hi, In Espressif documentations (ESP32-S2, S3, C3) it is adviced to use a RC network made of 10k resistor to VCC and 1uF capacitor to GND. But in most schematics a 0.1uF capacitor is used. My question is what value one must use? Same for "boot" pin. 1k resistor and 10pF capacitor. Is that good? Than...

Native USB issue on an esp32-s2-solo module (not kit)

Hi, Using an esp32-c3 module (Ai-Thinker one), I can use native usb either in run mode or DFU mode. With an esp32-s2-solo (a module not a kit), I can see the device in /dev only in DFU mode, not in RUN mode. I have a RC network (10kohm to Vcc/1uF to GND). I enter DFU mode by connecting IO0 to GND th...

Re: Compilation fails when using esp_apptrace_init() - JTAG

Thanks for your reply @lbernstone

I don't understand what you mean by "a customized sdkconfig".
Is there a doc somewhere?

Compilation fails when using esp_apptrace_init() - JTAG

Hello everyone. I'm trying to build a small program for testing JTAG 2-ways communication. I have the error: /Users/nb/.platformio/packages/toolchain-xtensa-esp32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: /Users/nb/.platformio/packages/framework-arduinoespressif32/to...

Re: Sending commands via JTAG to the esp32.

Hi CKiamy, I have found this: #include "esp_app_trace.h" . . . char buf[32]; char down_buf[32]; size_t sz = sizeof(buf); /* config down buffer */ esp_apptrace_down_buffer_config((uint8_t*) down_buf, sizeof(down_buf)); /* check for incoming data and read them if any */ esp_err_t res = esp_apptrace_re...

Re: Sending commands via JTAG to the esp32.

Hi,

Did you find a way to do that?
I'm very interesting.

Re: ESP32-S2-DevKitM-1 vs ESP32-S2-DevKitC-1R

Thanks @ESP_krzychb
8,74mm is a real difference indeed.

For the PSRam, I think it's the same. I was wrong when saying ESP32-S2-DevKitM-1, it was in fact ESP32-S2-DevKitM-1-N4R2.

Thanks again.
