cant flash latest m5 stamp c3

i CAN flash all other products as long as it's esp32, this one is esp32c3 and failes:
/vol/src/esp/esp-idf/components/esptool_py/esptool/esptool.py -p /dev/ttyU1 --before default_reset --after hard_reset --chip esp32c3 erase_flash
esptool.py v3.2-dev
Serial port /dev/ttyU1
Connecting...
Failed to get PID of a device on /dev/ttyU1, using standard reset sequence.
......
Chip is ESP32-C3 (revision 3)
Features: Wi-Fi
Crystal is 40MHz
MAC: 7c:df:a1:a3:61:74
Uploading stub...A fatal error occurred: Failed to write to target RAM (result was 01070000)

I have this issue as well and seams to be a known issues with ESP-IDF.
Unfortunately there is no UIFlow yet :( -
Hi guys
I think it heavily depends on the OS you are using. On my Ubuntu 20.04 desktop installation I have no issues compiling the ESP-IDF blink example and flashing it onto my M5Stamp C3. And as an added bonus Ubuntu even has the proper USB driver pre-installed.
Thanks

@felmue
thanks for the info, questions:
1- what version of idf
2- what baudrate -
-
after much work, got esp-idf to work on a Mac running Big Sur, and
get the same error. I'm waiting to receive a esp32c3 not from M5 to see
if it has the same issues. BTW, espressif is very silent
bleeding edge of technology :-( -

indeed, using different ttl-to-usb I managed to flash it. Had to manually
enter load mode (grounding pin 9) and now all is ok.

thanksWhat ttl2usb driver did you use?

Hi guys
I've just tried flashing my M5StampC3 through its built-in USB. Worked like a charm.
Note: I am using Ubuntu 20.04 so your mileage might vary.
Thanks

A fatal error occurred: Failed to write to target RAM (result was 01070000)Is there a usb driver missing? How to get and install?

Hello @HaSch
sorry, I don't know if you're missing a driver or not. On Ubuntu 20.04 there was no need to install a driver. Whatever is required seems to already be included in the stock version of Ubuntu 20.04.
I was wondering, in your case it fails while 'Uploading stub' which as I understand is not necessarily needed. In
menuconfigthere is an optionSerial flasher config-Disable download stubwhich by default is unchecked. Maybe try to disable the downloading of the stub and see if that gets you any further.BTW: what operation system and version are you using? Window? MacOS?
Thanks

I'm sorry, I'm using Arduino IDE and there is no menuconfig. But I have "USB CDC On Boot". Should it be enable or disable? I'm on a Mac with MacOS 10.15.7 Catalina.

Hello @HaSch
well, disabling downloading the stub doesn't help anyway - so my idea is moot. I've just setup a machine with macOS Big Sur 11.5.2 and with or w/o downloading the stub the download process ends in an timeout error.
What worked for me on macOS Big Sur 11.5.2 however is using the ESP32C3 built-in USB via GPIO18 and GPIO19.
Thanks

FelixIt really seems to be an issue with USB serial driver. I also tried to download and install the CH9102_VCP_SER_MacOS driver from here without success. Trying to install to my MacOS 10.15.7 Catalina ends up with an error:

I urgently need a working driver for m5stamp c3 for MacOS 10.15.7 Catalina. I tried to get it work via GPIO18 and GPIO19 but don't know how because there is no driver for that on my system. Using USB-C ist throwing the known error because of the wrong or incomplete driver. Even downloading and installing the suggested driver didn't solve the problem.

Hello @HaSch
sorry, I cannot help you with macOS 10.15.7 Catalina. I don't own any Apple hardware recent enough to run that version of macOS. Do you have access to another computer?
Thanks

Catalina is bugged since Apple released the OSX update, you need a full OSX update to 10.16 or try another TTL USB to UART adapter.

It's the built in adapter of M5Stamp C3!
-
Hello @ajb2k3
As an experiment I've tried to use another TTL USB UART adapter as you suggested, but it did not work. I suspect the adapter built into the C3 is interfering with some data lines.
Did you have success with another TTL USB UART adapter? If yes, how did you wire it?
Thanks
Felix
