a bit of guidance please... I've googled/forum'd - sure its simple, just cant get it working.
I have a MR33 trying to get OpenWRT onto.
Fedora 22 machine with Ethernet connection to the MR33, and serial port setup.
Wireless port enabled on the Fedora22 machine to download updates/configs etc as required.
The USB adapter I ordered is "Yizhet 2PCS CP2102 USB to TTL Serial Converter with 5 PIN Jumper Wire Cable Chip Compatible with Arduino, Windows 7, 8, 10, Linux, Mac OS X"
If I connect to the MR33 from the Fedora22 machine with wifi, i.e. connecting to 'Meraki Scanning' and access 10.128.128.128 via a browser, my Fedora22 gets the IP 10.118.117.35 and I can connect. I can download the support data (no option for f/w upload) but the DAT file is binary, and not sure how to extract this.
Attached putty log shows serial port is fine.... But
If I try the serial u-boot approach, I get this:
[root@localhost tmp]# ./ubootwrite.py --write=mr33-uboot.bin Uploading image Prompt is 'RNING! THIS CONSOLE IS LOGGED! UNAUTHORIZED ACCESS FORBIDDEN! <Meraki> ' Found an error, so aborting Uploading image
Or a similar variation like
[root@localhost tmp]# ./ubootwrite.py --write=mr33-uboot.bin Uploading image Prompt is 'eraki> ' Found an error, so aborting Uploading image
