M4 Board - Execution doesn't work from XFER

[Targhan]

I've used the M4 Board by @Duke for years, and now for some reasons I cannot make the execution of SNA or any BIN work thanks to XFER (I tested both the C and Python version, same result).
The upload/download works without any problem, the reset function, so does the website.

When uploading/executing, the CPC just resets, and nothing is launched, so the Amsdos is initialized normally. What could be wrong? Does it has anything to do with the fact that I use UniDos (hello @OffseT ) with the M4 node? Using the ùsna command does not work ("Failed to load snapshot").

What am I doing wrong? Thanks!

UniDOS M4 node does not interact with remote features of the M4 Board.
It should not change the behavior.
 
That said, on CPC side, you must pay attention to the fact that |SNA is restricted to files from the Library (like |DSK and |CPR). SNA, DSK and CPR files located outside of the Library cannot be accessed.

I think (I'm pretty sure in fact) you need to have a /tmp folder in the root of the SD

Thanks for your answers.

@OffseT Yes, the SNA is in Library.

@krusty_benediction The tmp is only useful when using the single-instruction to upload and execute at the same time. But yeah it is there, and even though the execution doesn't work as expected, the upload file is well here. Even doing it in two steps doesn't work .

SNA v2 vs SNA v3 ?

I daily launch snapshot from my PC to my CPC, but I'm not at home to check M4 rom version. I guess I have the latest one.
i do not use unidos. Sorry @OffseT

I use another tool to send snapshot and it downgrades sna V3 to sna V2 (although I have no idea if it is mandatory)
