问答对人有帮助，内容完整，我也想知道答案 0 硬件参照dm8127ipnc设计的，把dm8127做为u*的host，外接u盘，内核配置如下系统起来后，插入u盘，u盘指示灯是亮的，其他没有反应，内核有关u信息如下： root@dm8127-evm:~# dmesg \| grep u mu-hdrc: version 6.0, host, debug=0 mu-hdrc mu-hdrc.0: dma type: dma-cppi41 PM: Adding info for platform:nop_u_xceiv.0 u2phy: computed values rxcalib(15)DACs(35 12 14) u2phy: override computed values rxcalib(15)DACs(35 12 14) u2phy_config: mu(0) rxcalib done, rxcalib read value 6f71d976 mu-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) mu-hdrc: MHDRC RTL version 2.0 mu-hdrc: setup fifo_mode 4 mu-hdrc: 28/31 max ep, 16384/16384 memory mu-hdrc mu-hdrc.0: MUSB HDRC host driver mu-hdrc mu-hdrc.0: new USB bus registered, assigned bus number 1 u* u*1: New USB device found, idVendor=1d6b, idProduct=0002 u* u*1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 u* u*1: Product: MUSB HDRC host driver u* u*1: Manufacturer: Linux 2.6.37_DM8127_IPNC_3.80.00 mu-hcd u u1: SerialNumber: mu-hdrc.0 PM: Adding info for u:u1 PM: Adding info for u:1-0:1.0 PM: Adding info for No Bus:udev1.1 mu-hdrc mu-hdrc.0: USB Host mode controller at c581e000 using DMA, IRQ 18 Registered /proc/driver/mu_hdrc.0 mu-hdrc mu-hdrc.1: dma type: dma-cppi41 PM: Adding info for platform:nop_u_xceiv.1 u2phy: computed values rxcalib(15)DACs(31 16 17) u2phy: override computed values rxcalib(15)DACs(31 16 17) u2phy_config: mu(1) rxcalib done, rxcalib read value 6f6fe18e mu-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) mu-hdrc: MHDRC RTL version 2.0 mu-hdrc: setup fifo_mode 4 mu-hdrc: 28/31 max ep, 16384/16384 memory mu-hdrc mu-hdrc.1: MUSB HDRC host driver mu-hdrc mu-hdrc.1: new USB bus registered, assigned bus number 2 u* u*2: New USB device found, idVendor=1d6b, idProduct=0002 u* u*2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 u* u*2: Product: MUSB HDRC host driver u* u*2: Manufacturer: Linux 2.6.37_DM8127_IPNC_3.80.00 mu-hcd u u2: SerialNumber: mu-hdrc.1 PM: Adding info for u:u2 PM: Adding info for u:2-0:1.0 PM: Adding info for No Bus:udev2.1 mu-hdrc mu-hdrc.1: USB Host mode controller at c5828800 using DMA, IRQ 19 Registered /proc/driver/mu_hdrc.1 ucore: registered new interface driver u-storage ucore: registered new interface driver uhid uhid: USB HID core driver 系统打印信息如下： NAND read: device 0 offset 0x1c0000, size 0x400000 4194304 bytes read: OK ## Booting kernel from Legacy Image at 81000000 ...
