Hi,
I'm trying to do RX-TX loopback in fx3
dmaCfg.prodSckId = CY_U3P_PIB_SOCKET_0;
dmaCfg.consSckId = CY_U3P_PIB_SOCKET_3;
and its working, but getting dropped signal on TX.
FPGA signals show should_tx/can_tx much smaller then should_rx/can_rx
tried different samplerates, but same result always.
any ideas?

Re: RX-TX firmware loopback
Are you doing FX3 firmware loopback? I don't think that has anything to do with the FPGA and is really just an internal loopback in the FX3.
I am actually surprised the FPGA gets the samples at all.
If there is an issue, I don't think the FPGA will be the place you will find the issue with FX3 firmware loopback.
