I read this page tried to flash my Meraki MR33 to openwrt:
When i did the 1th step:run this command:# ubootwrite.py --write=mr33-uboot.bin
ubuntu PC(installed python、serial and minicom):
"Add images to do an installation via bootloader:
0. open up the MR33 and connect the serial console.
start the 2nd stage bootloader transfer from client pc:
ubootwrite.py --write=mr33-uboot.bin
(The ubootwrite tool will interrupt the boot-process and hence
it needs to listen for cues. If the connection is bad (due to
the low-profile pins), the tool can fail multiple times and in
weird ways. If you are not sure, just use a terminal program
and see what the device is doing there."
I had this questions:
1、What floder can I put the files:"ubootwrite.py"and "mr33-boot.bin";
to answer your question: anywhere on your workstation.
but you should have a look at the mr33 device page, get the installation package from google drive, and follow the instructions in the provided PDF document.
are you working with the flashing instructions for the MR33? Point 6 on page 7 tells you to upload the initramfs image (not the sysupgrade file).
the MR33 will listen for the TFTP transfer on 192.168.1.1.
your workstation should have some other IP address on the 192.168.1.0 network. You may want to temporarily disable the firewall on your workstation.
