Hello, I am working to port NuttX on a board based on STM32F4DISCOVERY. The microcontroller is the STM32F407VET6.
USB CDC support is not initializing. When I plug the USB on the board, I have the following dmesg response in Linux: [517062.075048] usb usb1-port2: attempt power cycle [517062.726922] usb 1-2: new full-speed USB device number 47 using xhci_hcd [517062.727170] usb 1-2: Device not responding to setup address. [517062.935148] usb 1-2: Device not responding to setup address. [517063.142906] usb 1-2: device not accepting address 47, error -71 [517063.270916] usb 1-2: new full-speed USB device number 48 using xhci_hcd [517063.271141] usb 1-2: Device not responding to setup address. [517063.479134] usb 1-2: Device not responding to setup address. When I run stm32f4discovery:usbnsh on my discovery board, it works. I compared the defconfig from the base project and from mine and I believe I have initialized everything that is related to the USB. Here is the defconfig for my board: # # This file is autogenerated: PLEASE DO NOT EDIT IT. # # You can use "make menuconfig" to make any modifications to the installed .config file. # You can then do "make savedefconfig" to generate a new defconfig file that includes your # modifications. # # CONFIG_ARCH_FPU is not set # CONFIG_MMCSD_MMCSUPPORT is not set # CONFIG_MMCSD_SPI is not set # CONFIG_NSH_ARGCAT is not set # CONFIG_NSH_CMDOPT_HEXDUMP is not set # CONFIG_NSH_CMDPARMS is not set CONFIG_ADC=y CONFIG_ANALOG=y CONFIG_ARCH="arm" CONFIG_ARCH_BOARD="phi-innovations" CONFIG_ARCH_BOARD_STM32F4_PHI_IOT_GATEWAY=y CONFIG_ARCH_CHIP="stm32" CONFIG_ARCH_CHIP_STM32=y CONFIG_ARCH_CHIP_STM32F407VG=y CONFIG_ARCH_STACKDUMP=y CONFIG_ARMV7M_MEMCPY=y CONFIG_BOARDCTL_RESET=y CONFIG_BOARDCTL_UNIQUEID=y CONFIG_BOARDCTL_USBDEVCTRL=y CONFIG_BOARD_LOOPSPERMSEC=16717 CONFIG_BUILTIN=y CONFIG_CDCACM=y CONFIG_CDCACM_CONSOLE=y CONFIG_CDCACM_RXBUFSIZE=256 CONFIG_CDCACM_TXBUFSIZE=256 CONFIG_CLOCK_MONOTONIC=y CONFIG_CONSOLE_SYSLOG=y CONFIG_DEBUG_ASSERTIONS=y CONFIG_DEBUG_DMA=y CONFIG_DEBUG_DMA_ERROR=y CONFIG_DEBUG_DMA_INFO=y CONFIG_DEBUG_DMA_WARN=y CONFIG_DEBUG_ERROR=y CONFIG_DEBUG_FEATURES=y CONFIG_DEBUG_FS=y CONFIG_DEBUG_FS_ERROR=y CONFIG_DEBUG_FS_WARN=y CONFIG_DEBUG_FULLOPT=y CONFIG_DEBUG_HARDFAULT_ALERT=y CONFIG_DEBUG_INFO=y CONFIG_DEBUG_NET=y CONFIG_DEBUG_NET_ERROR=y CONFIG_DEBUG_NET_INFO=y CONFIG_DEBUG_NET_WARN=y CONFIG_DEBUG_RTC=y CONFIG_DEBUG_RTC_ERROR=y CONFIG_DEBUG_RTC_INFO=y CONFIG_DEBUG_RTC_WARN=y CONFIG_DEBUG_SYMBOLS=y CONFIG_DEBUG_WARN=y CONFIG_DEV_GPIO=y CONFIG_ETH0_PHY_LAN8742A=y CONFIG_EXAMPLES_PPPD=y CONFIG_FAT_LCNAMES=y CONFIG_FAT_LFN=y CONFIG_FS_FAT=y CONFIG_FS_PROCFS=y CONFIG_FS_SMARTFS=y CONFIG_HAVE_CXX=y CONFIG_HAVE_CXXINITIALIZE=y CONFIG_HEAP_COLORATION=y CONFIG_IDLETHREAD_STACKSIZE=2048 CONFIG_INTELHEX_BINARY=y CONFIG_IOEXPANDER=y CONFIG_LIB_HOSTNAME="STM32F4-Discovery" CONFIG_MAX_TASKS=16 CONFIG_MMCSD=y CONFIG_MMCSD_MULTIBLOCK_DISABLE=y CONFIG_MMCSD_SDIO=y CONFIG_MTD=y CONFIG_MTD_MX25L=y CONFIG_MTD_SMART=y CONFIG_MTD_SMART_FSCK=y CONFIG_MX25L_SPIFREQUENCY=21000000 CONFIG_NET=y CONFIG_NETDB_DNSCLIENT=y CONFIG_NETINIT_DEBUG=y CONFIG_NETINIT_DHCPC=y CONFIG_NETINIT_DNS=y CONFIG_NETINIT_DNSIPADDR=0x08080808 CONFIG_NETINIT_DRIPADDR=0x0a010101 CONFIG_NETINIT_NOMAC=y CONFIG_NETINIT_THREAD=y CONFIG_NETUTILS_DHCPC=y CONFIG_NETUTILS_NETCAT=y CONFIG_NETUTILS_PPPD_PAP=y CONFIG_NET_ARP_DUMP=y CONFIG_NET_ARP_SEND=y CONFIG_NET_BROADCAST=y CONFIG_NET_ETH_PKTSIZE=1294 CONFIG_NET_ICMP=y CONFIG_NET_ICMP_SOCKET=y CONFIG_NET_SOCKOPTS=y CONFIG_NET_SOLINGER=y CONFIG_NET_STATISTICS=y CONFIG_NET_TCP=y CONFIG_NET_TCPBACKLOG=y CONFIG_NET_TCPURGDATA=y CONFIG_NET_TCP_KEEPALIVE=y CONFIG_NET_TCP_WRITE_BUFFERS=y CONFIG_NET_UDP=y CONFIG_NET_UDP_CHECKSUMS=y CONFIG_NFILE_DESCRIPTORS=8 CONFIG_NSH_ARCHINIT=y CONFIG_NSH_BUILTIN_APPS=y CONFIG_NSH_DISABLE_LOSMART=y CONFIG_NSH_FILEIOSIZE=512 CONFIG_NSH_LINELEN=64 CONFIG_NSH_PROMPT_STRING="nsh$ " CONFIG_NSH_READLINE=y CONFIG_PREALLOC_TIMERS=4 CONFIG_RAM_SIZE=114688 CONFIG_RAM_START=0x20000000 CONFIG_RAW_BINARY=y CONFIG_RR_INTERVAL=200 CONFIG_RTC=y CONFIG_RTC_EXTERNAL=y CONFIG_RTC_PCF8563=y CONFIG_SCHED_HPWORK=y CONFIG_SCHED_HPWORKPRIORITY=192 CONFIG_SCHED_WAITPID=y CONFIG_SDCLONE_DISABLE=y CONFIG_STACK_COLORATION=y CONFIG_START_DAY=13 CONFIG_START_MONTH=9 CONFIG_START_YEAR=2014 CONFIG_STM32F4DISBB=y CONFIG_STM32_ADC1=y CONFIG_STM32_DMA1=y CONFIG_STM32_DMA2=y CONFIG_STM32_DMACAPABLE=y CONFIG_STM32_ETHMAC=y CONFIG_STM32_I2C1=y CONFIG_STM32_JTAG_SW_ENABLE=y CONFIG_STM32_OTGFS=y CONFIG_STM32_PHYADDR=0 CONFIG_STM32_PHYSR=31 CONFIG_STM32_PHYSR_100FD=0x0018 CONFIG_STM32_PHYSR_100HD=0x0008 CONFIG_STM32_PHYSR_10FD=0x0014 CONFIG_STM32_PHYSR_10HD=0x0004 CONFIG_STM32_PHYSR_ALTCONFIG=y CONFIG_STM32_PHYSR_ALTMODE=0x001c CONFIG_STM32_PWR=y CONFIG_STM32_RMII_EXTCLK=y CONFIG_STM32_SDIO=y CONFIG_STM32_SPI1=y CONFIG_STM32_USART1=y CONFIG_STM32_USART2=y CONFIG_STM32_USART3=y CONFIG_STM32_USART6=y CONFIG_SYSTEM_NSH=y CONFIG_SYSTEM_PING=y CONFIG_USART2_IFLOWCONTROL=y CONFIG_USART2_OFLOWCONTROL=y CONFIG_USART3_RS485=y CONFIG_USART6_RXBUFSIZE=64 CONFIG_USART6_TXBUFSIZE=64 CONFIG_USBDEV=y CONFIG_USER_ENTRYPOINT="nsh_main" I believe that there is something missing or wrong in my configuration, but I couldn't find what it is. Can anybody give me some advice on how to solve this issue?
