Hi all,
I am using the geprc mark 5 with the dji o3 bnf.
I have run into a problem flashing my rx. I have tried through the Elrs configurator using betaflight passthrough but each time if fails to locate the COM port. I have tried installing and running the impulse osd driver file and no dice also the stm driver for flashing.
No luck with this I also tried wifi flashing but my pc refuses to pickup the rx wifi network so I sent the build file to my phone and when I connect to the webpage and upload the file it states there is not enough space on the reciever to complete the flash (I can’t remember the specific error but will create it when I am home in the morning.

I should note I did have everything working and ran about 20 packs until I uploaded the geprc cli dump because I wanted the stock PID tune for the mark 5.

I had same issue with that.The installer(flasher) accept only .gz files, because they are compressed.Do not extract this .bin file.

it will also accept .bin, if it's a smaller file size

#

(e.g. older firmware version)

Ok

#

But not new one, right?

#

if by some miracle, the newer version of the firmware will be smaller, say a way to optimize it is found, then maybe..

#

if that day comes, then you'll read about it in the guide

And then comes the message not enough space?

glacial jay And then comes the message not enough space?

if the firmware is smaller and fits within that space, then there is enough space..

#

but until that day comes, use the firmware.bin.gz
