new m5stack: Failed to write to target RAM (result was 01070000)

@zontex Thanks a lot! Email sent with the full explanation of the issue

Hello @Zontex could you advise me also as I got a similar problem
Start Burn

I guess it is the driver not loading well as I can only see this tty of type modem but I have found no easy way to make it working, I am using the Apple Multi Adaptor (HDMI/USB) on USB C.

I have installed latest driver https://www.silabs.com/documents/public/software/Mac_OSX_VCP_Driver.zip and can see the corresponding extension in /Library/Extensions with
drwxr-xr-x@ 3 root wheel 96 Oct 15 10:46 SiLabsUSBDriver.kext
but then when running M5Burner it only show a tty device of type Bluetooth or usb modem
ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port
/dev/tty.usbmodem51850037101I am running macOS Catalina

/dev/tty.usbmodem51850037101 is the correct device, I'm not sure what's going on in OSX but this is how it appears for me and the device that works for me.

Great thanks, I will try again later, in the meantime I switched to a Windows machine to make it working.

I had weird problems like this with an M5Stamp-PICO until I put more capacitance across the bus (5V and 3.3V). I used a couple of tantalum capacitors I had on hand, not sure the value, probably 33uF. I was powering the device through the USB serial adapter and apparently it was power limited.
I have had no problem whatsoever since then. -

Same here - Have You found any solution?
-
This was a known issue with Big Sur (something related to the python and / or serial port implementation in Big Sur.
I did contact M5Stack support but no solution has ever been found.
I gave up and reverted back to Catalina and it worked fine again.
Now I just installed the latest Monterey but haven't tested the Core2 yet.
In the meantime I was also using a windows computer.... -
@erich I'm on Mojave 10.14 and problem still exists :/
-
I’m actually getting it with Catalina
-
Has anyone managed to get the core 2 to work with an M1 mac? I think that you do not need the driver for the m1? With a m5stick C it works fine, but not with the core 2

I have the same issue when I use the M5Stack ESP32 Downloader.
However when I use a simple M5Stack Atom Matrix, its works fine.I am on OSX Big Sir.
I feel like the issue is related to the CH9102 chip on the ESP32 Downloader where the Atom has the CP2104 I think.
This theory is supported by this article here:
https://blog.squix.org/2021/08/ch9102-driver-issues-failed-to-write-to-target-ram.htmlConfirmed, installing the driver from this thread here worked for me

https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/issues/139I guess you're right as I noticed on banggood/ aliexpress some products using this CH9102 chip are tagged as not Mac compatible.

@mackone try connecting the downloader's 3V3 to Stamp Pico's 5V
-
I found a solution that works on Montery :-)
Make sure you follow the PDF instructions, this works M1 Mac M5 Epaper
-
@parahooner Very many thanks for posting this, it completely resolved the problem.
-
I still have the same problem with 5 new M5Fire on Big Sur. Two older ones burned succesful.
-
@drjakob Check which USB driver is in the new cores as the driver chip was changed due to the part shortage.
