| 我们想扩展3588S的USB3.0接口的数量，以3588SJD4的开发板为例，如果插上一个mini PCIe转USB3.0的转接卡，是否可以支持呢？ 我这边手上有一个 https://item.taobao.com/item.htm?id=41485814386 这样的转接卡，插上去后看起来没有反应，我这边已经使用大4PIN转小4PIN的电源线给转接卡供电了，但是lspci并没有任何反应，而且插上U盘也一样没有任何反应，请问下是否需要修改设备树重新编译固件才可以？谢谢。 $ lspci -vv 0004:40:00.0 PCI bridge: Fuzhou Rockchip Electronics Co., Ltd Device 3588 (rev 01) (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR+ <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 129 Bus: primary=00, secondary=00, subordinate=00, sec-latency=0 I/O behind bridge: 00000000-00000fff [size=4K] Memory behind bridge: 00000000-000fffff [size=1M] Prefetchable memory behind bridge: 0000000000000000-00000000000fffff [size=1M] Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- Expansion ROM at f4800000 [virtual] [disabled] [size=64K] BridgeCtl: Parity- SERR- NoISA- VGA- VGA16- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: <access denied> Kernel driver in use: pcieport lspci: Unable to load libkmod resources: error -12 0004:41:00.0 Network controller: Broadcom Inc. and subsidiaries Device 449d (rev 02) Subsystem: Broadcom Inc. and subsidiaries Device aae8 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 128 Region 0: Memory at f4200000 (64-bit, non-prefetchable) [size=64K] Region 2: Memory at f4400000 (64-bit, non-prefetchable) [size=4M] Capabilities: <access denied> Kernel driver in use: pcieh |
