Re: [uracoli-devel] WiBO: not checking for CRC?

[Daniel Thiele]

Hi Tomás,

 

thats exactly what its doing: Count CRC during receiving firmware on both sides (Wibo + Host) and compare at the end.

In the Python app, the function WIBONetwork.checkcrc() (wibohost.py:301) is doing this and returns True or False. Of course, this can not be done via broadcasting but for each node sequentially. When using the command line interface this is done for all nodes being flashed and result is output to stdout. I see in each affected call (wibohost.py:420 and 449) there is a TODO comment. Maybe there is something to improve?

What do you see? How do you use the Python class? Instantiate WIBONetwork directly or use the command line interface?

 

Best,

Daniel

Betreff: [uracoli-devel] WiBO: not checking for CRC?

 

I got lost on the commands when using WiBo.

How do you check if a sent program has been sent correctly?

 

I was thinking that after sending the whole program, one would ask for the CRC of the received program and compare it to the local one on the computer.

 

Is this done?

If so, where (I'm using the python app to send the the new firmware but want to check the if it's been sent correctly before exiting the bootloader)?
