I am using Windows 7 for the development and I am follow the instruction (https://www.raspberrypi.org/documentati ... lashing.md
) to flash the CM3 board eMMC, i tried the "WINDOWS INSTALLER" section, but when the CM3 board plug into the computer USB port, the board is recognized as "Microsoft XBox Controller Type S" device. Hence, i uninstall the device from the "Device Manager".
After uninstall it, i see the CM3 board recognized as "BCM2710 Boot" in the "Device Manager". Then i manually select "Let me pick from a list of device drivers on my computer", if i select "Universal Serial Bus devices", then i see a list of "Microsoft Xbox Controller Type S" for me to choose from. If i select "libusb (WinUSB) devices", then i can select "BCM270x Boot". I think "BCM270x Boot" is the device that i should select.
After all the installation, when i launch the program "rpiboot.exe". this is what i see,
waiting for BCM2835/6/7
Failed control transfer
Failed to write correct length, returned -7
Then this 4 sentences are keep repeating.
Since i have the issue of using the window installer method, I have tried the "MANUAL CYGWIN INSTALL" method run in windows 7 in the instruction also but same issue happened to me. Can anyone help to support to solve the eMMC flashing issue?
BTw, anyone know why when the device first plug in to the computer, it shows "BCM2710", but when i do the driver installation, the driver can be selected is "BCM270x"? is the issue caused by the driver provided not compatible to the CM3 hardware? The microcontroller used in this board is BCM2837, what is the meaning of the above mentioned BCM2710 and BCM270x?
