Hi guys,
I’m have trouble using cube programmer to erase the native at-firmware from wio-e5 mini.
I’m able to connect with serial to use the at command but when I open the cube programmer, no device is detected.
I couldn’t find any document detailing what to do.
does anyone else have the similar problem?
Can someone help please?
Thank you very much.
Hello, how did you connect it to the computer, and can you provide the wiring diagram?
It is not enough just to power the STM32Cube via USB-C. If you want to develop with the STM32Cube, you also need to prepare an ST-link as described in the Wiki above and connect it to the PC via the SWD pin.
I’ve just received two of these devices in the post. It’s interesting to me that it was marketed as a dev board at all.
This is a product that ships with read protected firmware and no way to erase/program it via USB. Easily flashing via USB is really the feature which makes a product a “dev” board, as you can flash just about anything with an ST MCU if you have an SWD/JTAG programmer, which is what this board requires. And then if you do go through the effort of removing the RDP with an st-link (a seperate purchase) you can’t restore the original AT firmware. To top it off, you still can’t reliably use the ST boot loader to flash via USB as they haven’t broken out the BOOT0 pin. Meaning you have to hook up SWD again!
Wish I’d done more research before purchasing as I feel misled about what I was actually getting. I see Seeed has plainly explained this in their docs, but frankly, it just shouldn’t have been done like this and marketed the way it is. It’s a LoRa module.
Unfortunatly it happens all the time…
Hi there,
I would agree with the OP on the DEV classification, 
I think Seeed maybe was misled by the creator or chip supplier on the NON-Open Source of the bootloader , from which everything and anything is possible. The Whole AT firmware Malarky is just a barrier to True development on these platforms, is it me or do things seem to becoming more closed in LORA and proprietary than before, IDK ? SMH on this one.

yes there is something secret about the AT firmware that is propritary or something… i guess if someone pays you to make a model T ford… you make a model T ford… What Da?
