[Oberon] Oberon RS232 - file exchange with Linux / OLR for RPI

[thomas.kral at email.cz]

Peter,

Thanks for explaining now I see.

I have RISC5 (FPGA Project Oberon 2013) connected to RPI running OLR.
I wanted to exchange files using PCLink1 task at RISC5 end with ORC master/client on RPI end, as ORC is part of the project.

Meanwhile I managed my 1st file exchange right from Linux shell, file is <255 bytes in length = 1 block.
It took me a very long time to discover that name is NULL terminated, I was putting leading length byte in front first.

# send REC and file name terminated with NULL!
$ echo -ne \\x21'Test.txt'\\0 > /dev/ttyUSB1

# copy one block <255 over line
$ cp Test.txt /dev/ttyUSB1

On Oberon screen I got .. 
receiving Test.txt done

So far so good -:)

Peter, is there a way to compile in modules for OLR/RPI to support 
 /dev/ttyUSBn
Could you please advise?

This would allow to run ORC master client, which really is the way to exchange files and also boot RISC5 over RS232 as documented in the project.

Many thanks so far
Tomas

Hi Tomas,

I was only following this thread half way.

Turns out, you want to connect something via V24 to OLR.

Well, V24 like Centronics and network only are dummy modules needed to 
compile other Modules. So you currently have to transfer files via Linux.
