Unable to download firmware to ESP32-C3-C05

[alexlimbeck]

Hello.

I am trying to flash some ESP32-C3 based chips
(ESP32-C3-C05 produced by DOIT under Esapressif license, with just different pinout, to be pin-to-pin compatible with the Tuya Chips)

I am using latest Arduino IDE (2.3.4) with latest Espressif boards installed (3.0.7)

I tried to set all of ESP32-C3-based boards in Arduino IDE, but after successfull flashing, the result vary in some similar messages:

ESP-ROM:esp32c3-api1-20210207
Build:Feb 7 2021
rst:0x1 (POWERON),boot:0xd (SPI_FAST_FLASH_BOOT)
SPIWP:0xee
mode:DIO, clock div:2
load:0x3fcd5820,len:0xf64
load:0x403cc710,len:0x73c
load:0x403ce710,len:0x2eb8
entry 0x403cc710

I tryed to sed upload speed, cpu speed, flash speed, erase flash during program... but with no luck.

Any help ?
Thanks.
