GetVersion function is fine, but the Update furnction does not work.
Please help! thanks.
I am using the original VirtualDevice_MCU.offer.bin and VirtualDevice_MCU.payload.bin as my input files.

In CFU Protocol Specification, Table 5.5 3 (FIRMWARE_UPDATE_CONTENT Header Bits) Data length field is limited to 8 bits in size.
It is also mentioned that "maximum allowed value for the length is 52 bytes".

Does this mean that the maximum allowed size in one payload transaction is 52 bytes?

Hi,
We want to upgrade our pnp device's fw through windows update, and the connect interface is i2c.
Does it reasonable to use i2c framework replace the hid? Or are there any other suggestions for fw upgrading through i2c path?
thanks!!

BR,

The descriptions and the bit indexes of these two bits are reversed in the table text. The bits are correct in the diagram, which corresponds to the driver.

Looks like when I install the CFU driver, it replaces the current device driver of the device I specify on the inf file on [Standard.NT$ARCH$] %ComponentFirmwareUpdate.DeviceDesc%
How do I keep the original device driver in addition to the CFU driver?

Hi All,

I follow the steps from CFU virtual HID device firmware update simulation and create a virtual device in device manager.

Than, I build the solutions "VirtualDeviceFirmwareUpdate.sln & CfuExample.sln" to generate .inf, .cat, .dll, two offers, two payloads and FwUpdateCfu.exe.
\CFU\Host\MonolithicPackageExample\VirtualDeviceFwUpdate\Debug\x64\VirtualDeviceFirmwareUpdatePackage\VirtualDeviceFirmwareUpdatePackage

When I try to execute tool, there is an error message:
FwUpdateCfu.exe version protocolCfgExample.cfg

Argv #1 is: version
Argv #2 is: protocolCfgExample.cfg
Error Device not found or not working

Here is content of my config:

#instructions:

#only the first 2 fields will be looked at so values after that are considered comments
VID,0x045e,#mandatory (each vendor must maintain their own Vendor defined Utility Page collections)

CONTENT_RESPONSE_INPUT_USAGE,0x66,#mandatory for fwUpdate procedure

Is there any advice ?

Thanks

Is there list of hardware that supports CFU? I'd like to add cfu support to fwupd and need some hardware to test the implementation. I'm especially interested in devices that have subcomponents with different firmware versions. Thanks.

How can we apply this CFU for PCIe/NVMe SSD device?
Please give us some advice or reference code for this design, we check current CFU just are for the HID device but there have no define for storage devices,

Best regards,

The keyboard ids of my Microsoft Surface Book Gen 1 matchs the example configuration with VID=045e and PID=07cd
I tried FwUpdateCfu.exe version with the configuration example on this Microsoft Surface Book Gen 1 , but I am getting "Error Device not found or not working".
What steps I am missing to get the FwUpdateCfu.exe version to run?

Hello dear IT worker,

Does this github is a bad fork ?

How to install this github by make and configure Line of command ?

Does this github bring support for HEIC code ?

Thank you in advance for yours answers,
