We've been buying ConnectME modules for a few years now.
Now however, we've got a batch that seems to crash when we flash our own firmware.
The ones that're working are called:
PN: 50000878-03 AA -C
The ones that're not working are called:
PN: 50000878-03 AD -C
We flash it by ftp. We first flash our bootloader, waits for it to finish and reboot and then we flash our image and waits for it to reboot. When it reboot after the image, it seems to come up and then it disappears from the network. (I assume it crashes.)
I think our NET+OS is v.7.5.
So, what's going on? Anyone knows what the AA/AD signifies?
