Hello,
I am new to the Toolfow and I have been following the Red Pitaya tutorials.
I have Matlab 2018 and Vivado 2019 installed. I was able to follow the
first two tutorials which compiled and uploaded via casperfpga
successfully. When following the wide band spectrometer tutorial I tried to
program the red Pitaya with the fpg file provided for the tutorial here
<https://github.com/casper-astro/tutorials_devel/tree/master/red_pitaya/tut_spec>,
but got the following response/error;
Connecting to Red Pitaya: 192.168.200.151
Uploading: tut_spec.fpg
These are the devices in your design ...
['acc_cnt', 'acc_len', 'accum0_snap_ss_bram', 'accum0_snap_ss_ctrl',

bram_dmp['length'] / (self.width_bits / 8)))
RuntimeError: accum0_snap_ss.read_uint() - expected 16384 bytes, got 32
I also tried compiling the .slx file and got the same error while trying to
upload and program.
The version of casperfpga and mlib_devel are as follows:
mlib_devel commit id = a9e87d994cf5f512fa0ea555ec7495d8dedc0855
caspserfpga commit id = c2258ea014340a7376d504e7128198ed2cfa5442
What could be the problem?
Thanks,
Paul.
