ESP32 Forum

I've developed a new hardware, which is first ESP32-S3 design for me. Before I ve used XIAO ESP32S3 board. With new design I have some problems
1- If I connect my hardware to PC via USB 2.0 cable (in the meantime, I ve checked USB cable with XIAO ESP32S3 board, it works), device manager begin to refreshing itself, why is that occur? I ve used in my hardware two different ESP32S3 chip (ESP32S3-R8 and ESP32S3-FH4R2) for two prototypes.
2- Although device manager frequently refreshing itself, I can connect to chip via cmd prompt as following code:
python -m esptool --chip esp32s3 --baud 9600 --port COM10 flash_id
esptool.py v4.5.1
Serial port COM10
Connecting...
Chip is ESP32-S3 (revision v0.1)
Features: WiFi, BLE
Crystal is 40MHz
MAC: dc:54:75:d6:c2:bc

Stub running...
Manufacturer: c8
Device: 4017
Detected flash size: 8MB
Flash type set in eFuse: quad (4 data lines)
Hard resetting via RTS pin...
and additionally, After erasing flash via cmd , then refreshing has gone. But If I disconnect hardware and connect again continue refreshing.

3- If I try to erase flash, I can, but If I try to upload any firmware XIAO ESP32S3, of Adafruit etc, I got always following error message:
python -m esptool --chip esp32s3 --baud 9600 --port COM10 write_flash 0x0 "C:\Users\hankishan\Downloads\XIAO_ESP32S3_v1.1_SCH&PCB_230327\adafruit-circuitpython-lolin_s3_mini-en_US-8.2.1.bin"

The my question is "Is there any problem in my hardware? or May I forget somethink in my schematic?, or May I wrongly connect any pin connections?, or Is other else ?", I ve shared with you as a schematic (Main & power design),To looking at the all forums, and Applied all of them, But I got the same problem again.

I ve found the problem. The problem is related to LDO regulator (MCP1700-3.3V, 250mAh), It limits the system current supply especially to ESP32S3, so ESP32S3 does not work correctly. After I changed it with AP2112K-3.3 then, the problem 's been solved.
I closed the post.
