We have the following models on APU2 family:
The schematic could be downloaded for all APU2 family boards from this
side.
See https://www.pcengines.ch/apu2.htm
They all use the similar PCB with some minimal changes.
APU2
2 mpcie slot
apu2d0 (2 GB DRAM, 2 i211AT NICs)
apu2d2 (2 GB DRAM, 3 i211AT NICs)
apu2d4 (4 GB DRAM, 3 i210AT NICs)
J14 (USB + SIM1) PE3_RST to GPIO G51
J13 (USB + SIM2) PE4_RST to GPIO G55
APU3
3 mpcie slot
apu3c2 (2 GB DRAM, 3 i211AT NICs, optimized for 3G/LTE modems)
apu3c4 (4 GB DRAM, 3 i211AT NICs, optimized for 3G/LTE modems)
J16 (PCIe + USB no SIM) not connected to a userland GPIO
J15 (USB SIM1) PE4_RST to GPIO G55
J14 (mSATA or USB SIM2) PE3_RST to GPIO G51
APU4
3 mpcie slot
apu4c2 (2 GB DRAM, 4 i211AT NICs)
apu4c4 (4 GB DRAM, 4 i211AT NICs)
J15 (PCIe + USB no SIM) not connected to a userland GPIO
J14 (USB SIM1) PE4_RST to GPIO G55
J13 (mSATA or USB SIM2) PE3_RST to GPIO G51
Please check again so that I have not done any mistake.
So all USB only mpcie slots could be reseted by a GPIO G51 and G55.
Kind regards
Flo
