I don’t know. I switched to arm64 and build for it. I was worried about the latency until I talked to Peter Wallace. Since the latency mainly runs about 3-13 us occasional bumps to 50us shouldn’t hurt a 100 us thread (because, as I understand it, Peter has implemented a PLL to keep things in sync). However, don’t listen to me, talk to Peter or maybe Peter will chime in a clarify for all of us. I bought a 7i76e to run off the RockPro64’s gigabit ethernet (doesn’t run off the USB). I don’t know how tight the timing is on your SPI stuff. > Got question on Rock64 since they came with almost zero docs, I note > there are 3 std sized usb ports, two have white plastic inserts, while > the single stack port adjacent to the pair has a robins egg blue plastic > insert.
