I am attempting to program an artemis module via uart interface and the ch340c chip and the arduino ide. The code compiles but then throws the error below when attempting to upload. Can anyone help me with this? This happens on multiple computers and operating systems. Thank you!
Artemis SVL Bootloader
Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.
…is the right COM port selected and the SVL bootloader being used? Go through this section https://learn.sparkfun.com/tutorials/de … rogramming as well
Was a solution found to this? I’m trying to program a Thing Plus Explorable using a new Macbook Pro (with Apple’s M2 Max silicon) and am getting this same error.
Thanks,

I am getting the same results, and it’s mystifying. Here’s the situation:
I have extensively used the Artemis Nano, Redboard and ATP for a couple of years without any problems. (They are running various programs used for a range of art pieces.) But when I recently purchased new boards, I got the abovementioned error message:
“Artemis SVL Bootloader Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.”
When I try to burn a new bootloader, it cannot connect over the serial port and the upload fails.
Here are the mysteries:
I am using a Macbook Pro M1 which has received all the operating system updates and is fully current. It has worked on these boards in the past, but no longer works, even on previously-purchased boards.
I restarted my previous Macbook Pro (the Touch Bar model), which has been neither updated nor used since 2022, and after loading the Sparkfun Apollo libraries into the Arduino app, it too receives the same error messages (it had not previously been used on these boards).
On a recently-purchased Artemis ATP, a program I run on other ATPs loaded on the first attempt, but all subsequent attempts have given me the above error messages. The only thing connected to that board was the USB-C cable.
(I’ve tried various cables and baud rates without success.)
The computer does connect to Raspberry Pi Pico2 and Arduinos without problems.
I’m really puzzled. Can anyone provide any suggestions as to how to re-establish working with these devices. I’m not particularly expert in these matters. Might I be overlooking something?
Any aid you can provide will be greatly appreciated.
It seems to happen with drivers every now and then when Apple releases some security update that doesn’t allow for for kind of serial enumeration, and it’ll generally be broken until they release a fix for whatever they’ve broken…This is just a side effect of Apple hardware/security and unfortunately there isn’t much to be done on our end :-/
Sometimes you can find workarounds folks have instituted online that use virtualization, adapters, or similar.
But in general I’d just recommend grabbing a cheap 2nd-hand laptop or something if it’s a dire necessity
Thank you for your illuminating response. I’ll just wait for Apple and in the meanwhile use RPi Pico 2s.
