That looks good for the SAMD51 firmware, and the version dated 2021-04-19 is more recent than the manufacturing date of my Board (2020-04-30), so its likely to be worthwhile to update.
Seed likely remove the link to that information because Espruino is no longer available. So they threw out the baby with the bath water. Who knows how Seeed think ?
Unfortunately that doesn’t help with update of the Quectel Modem. Which also has updated firmware available, and I have myself found a few bugs with it. As mentioned, I see a possible pathway to loading it (and the Quectel support guy informed me that I have to “reserve” the USB Port. for this task…). I will wait to see if someone else can help on this count.
The trick with the Boot + Reset button is now well enough known that someone else told me about that one, and I use it regularly.
Thanks for your help , and thanks to you I am one step closer.
Cheers
