ahhhhhh i see
ok right!

I could whip up a quick serial app to feed to file byte by byte if doing it that way.


OOooooo you got me super excited!!!!!!!!!!

Right, so if wanting to do the opposite, and read it from the module and TO the pc..

I could use cat MyDesiredFile.bin

Since its a binary file, its not going to be text, but if I get my own custom terminal to just read the bytes in and save to a bin file... that should work?

Yep. And you probably have options for stream redirection in whatever shell you have.. be it something unixy or powershell on windows or whatever your doing.

Did you ever get this working? I'm messing with the same type of cluster now. I was able to replicate Antus' proof of concept, but I can't send any meaningful data. It just crashes the serial console on the cluster, requiring a reboot. I'm using Realterm and I've tried messing with different inter-character delays. It doesn't seem to help.

We did. Its some time ago now but I believe we ended up having to overwrite another application with a custom linux one to allow us to transfer larger files without problems. In the end, it was alot of mucking around thus was not worth selling any options to customers (customizing themes, logos, custom screen parameters and displays).

Yeah, it seems like more of a pain than it's worth. I'll keep chasing the USB connection. It's pinned out on the development connector. I just need to figure out how to enable it.

Typically in start routines/scripts, they will have which debugging options are enabled/disabled, usually just a single comment away from enabling it.

They don't. This install is pretty lean. The USB driver is present on the file system, and I think I finally figured out how to start it, but I still can't get a response on the console or in the log when I pull the data pins up to 3.3v. I think there's a GPIO toggle needed to enable the 5v supply, but I'll be damned if I can out where that even comes from, let alone how to enable it.

Keep in mind that some serial debugs have their print enabled, but transmit disabled.
