Dear all,

I am in need of a little help, I have recently just purchased two LoRa expLoRaBLE Artemis boards and am having trouble uploading sketches to it, even the Blink sketch, I have tried changing baud rate and slowed it down as far as I could in Arduino IDE, and uploading new drivers, none of which worked. I am new to Artemis (not arduino) and am wondering if there is a method that I have not yet tried that would work? Btw I am on M1 apple silicon, and this is my first post!

Many thanks in advance APS

what error message do you get ? (if not enabled yet : file / preferences / check show verbose messages during upload)
You can try the Ambiq or the Sparkfun uploader?

[APS]

Sorry about that, the error message is as follows:

Artemis SVL Bootloader
Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.

Many thanks, APS

I have tried both Ambiq and SVL, but to no avail.

[paulvha]

Do you see a COM port to which the board should be connected? if not have you tried a different cable? some cables on provide power.
Is no Windows/Linux/Ubuntu computer available to try? else maybe someone else has an Apple M1 that can provide some help.

[APS]

Yes, I do see a COM port to connect to and the CH340 drivers are working, I have also tried many cables, is it worth trying this on my windows machine?

[paulvha]

Give it try on Windows ... just to be sure it is not the boards. All Artemis boards have the Ambiq loader or the SVL loader. In case of the SVL loader, you could try a lower speed. On my Ubuntu 460800 is the MAX. Above that it will fail 100% of the time. So maybe also try at 230400 or lower. If the SVL loader is on the board it will detect the speed automatically.

[APS]

I have tried on both Mac and Windows and have lowered the speed to 57600 baud, but still can't get it to work. Do you have any other suggestions?

[paulvha]

can you copy the exact error message you get ? maybe it provides a clue ?

[APS]

I get the same error message as before.

[paulvha]

is it ONLY..

Artemis SVL Bootloader
Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.

even with the verbose turned ON ?

[APS]

Sorry, forgot to turn on verbose.

Full error message is as follows:

Artemis SVL Bootloader
Script version 1.7

Phase: Setup
Cleared startup blip

Many thanks, APS

"Failed to enter bootload phase" means it can not detect the board as it did not get an answer (Timeout or CRC). It will try 3 times in the code based on the baudrate provided.
What does it say with the Ambiq loader with verbose?

However, on attempting it for a second time, it no longer works. Any idea why this is happening?
