ESP32-S3 not working with the CP2104
ESP32-S3 not working with the CP2104
My ESP32-S3 will not upload and Arduino sketch using the CP2104. I double checked the Rx Tx lines from the S3 to the CP2104 and have a 10K pull-up on IO0 but none on IO45 that I believe is correct. Attached is the schematic and upload errors. If anyone has any idea, it would really help. I find it odd that the chip appears to be detected but the sketch will not upload.

Re: ESP32-S3 not working with the CP2104
Your upload speed is close to 1MBaud. I'd start out by setting that to something lower first, see if that works.

The slowest upload speed has not fixed the issue.
