Hi there If you remain keen to read raw values from within the ppc you could use netcat (or your own socket) to localhost, port 7147 and issue ?read requests directly. Note that there are differences between read and wordread.
You could also pipe the text output of your ash script to gzip and compress it - that might save you space too... The reads from /proc/????/hw/ioreg were a thing on older software revisions and probably not available on the roach2 regards marc On Wed, Nov 20, 2019 at 1:48 PM Sebastian Antonio Jorquera Tapia < [email protected]> wrote: > Hello, > In the last days I start to thinking in reading the BRAMs on the fpga via > the PPC directly and not give the request via LAN reducing the reading > latency (I suppose) > Messing around inside the ppc, I found the command kcpcmd which enables me > to send katcp requests so thats nice.
