Arbitrary Signal Generator: Ch A buffer current read pointer on fpga_0.94 always read as 0 #1

Closed VacumMastah closed 1 year ago

VacumMastah commented 1 year ago

with /opt/redpitaya/fpga/fpga_0.93.bit the read pointer can be read, when the signal generator is running. (command "monitor 0x40200014")

With the version fpga_0.94.bit it always reads 0x00000000

How to trigger: generate 1 0.5 10000 tri monitor 0x40200014 --> 0x00000000 is read

cat /opt/redpitaya/fpga/fpga_0.93.bit > /dev/xdevcfg generate 1 0.5 10000 tri monitor 0x40200014 --> e.g. 0x0000dbb4 is read (the first read is always 0x00, too)

We need to fix the documentation. The register had to be moved to new offsets because we added a new feature in its place (very slow signal generation).

Channel A current read pointer is now at offset 0x60; Channel A current read pointer is now at offset 0x64;
