HP FPD inteface stuck when burst size is not power of 2

Hello,

I'm benchmarking the HP FPD slave interface of a TE0802 board featuring a xczu2cg-sbva484-1-e SOC.

I'm usign a custom AXI master to flood the interface with read or write operations.

I noticed that, when the burst size is not a power of two, the slave will eventually get stuck and stops replying to read requests.

I'm attaching two waveforms, showing a successful (burst 4) and and an unsuccessful (burst 3) case, with a reading benchmark.

Is there anything that I'm missing?

Thanks,

Marco
