Hi!

I am developing an application for the ESP32-P4 using TinyUSB, running on the USB Full-Speed port and I have issues with the low throughput of the USB CDC serial port.

During binary transfer to the virtual serial port (for example using command cat test.bin > /dev/ttyACM0) I am achieving only ...

Another observation - it looks like when I use DCDC converter and I add additional capacitor (which by documentation is not needed) between FB_DCDC and ESP_VDD_HP pins the processor starts to work fine. On the oscilloscope the voltage output of the DCDC converter gets more stable after that.
Are ...

sreejithrnair It would be better probably if you have asked that question in a separate thread :D

With further testing, by experimenting with HP Core clock frequency I was able to lower it to minimum, which is 40 MHz - at that frequency I was able to run LED blink program with HP Core voltage down ...

Hi there,
I am facing an issue with stability of my custom ESP32-P4 + ESP32 board.
It seems to only work reliably with HP Core voltage between 1.20 and 1.27v. These thresholds varies a bit from board to board, however the range is much smaller than one permitted by documentation (1.0 - 1.3v). Tests ...
