Hello Sacchetti Giampaolo, please share what arguments did you use to execute the python script?? Use '<<code>> <</code>>' to share the outputs from the console.

Hello,

what target are you trying to build? You are using default settings, have you checked that your KEIL installation matches the path which is set by default in scripts?

Hello Sacchetti Giampaolo,

the error is caused by not setting the path for fromelf (part of uvision installation). Please provide own private_settings.py file, where you set at least this 2 variables:

FROMELF = r'c:\\Keil\\ARM\\ARMCC\\bin\\fromelf.exe'
UV4 = r'C:\Keil\UV4\UV4.exe'

The scripts are not documented yet, many changes were there added lately, therefore we should update and expand it.

Regards, 0xc0170

Can I use this "flash_algo_gen.py" in PyOCD's flash algorithm?

You mean generated flash bob from that script to use in pyOCD?
