Problem downloading firmware to device with dfu-util was created by mbs
Hi, I'm trying to use linux to update the SDC21xxS firmware. I can use minicom to put the device into DFU mode, and then can upload and read the firmware from the device with dfu-util. I've tried to download the SDC21xxS firmware files (.zdfu and .zbin) to the device but both files have failed. I do not have much experience with DFU, STM or Roboteq devices, so I would be grateful for any help.

Which model controller and hardware revision are you using?

You will have to change the .zdfu folder to a .zip file, extract it, and then use the F3 dfu file with dfu-util. I believe the usage of the utility for dfu files is a
little different than what you have tried so far
.
Would you mind posting the memory that you were able to read from our controller using dfu-utils? We would like to see if the dfu-utility is working properly with the DFU mode implementation on our controller.

Thanks!
I was able to download the firmware (v18d) using dfu-util, but when uploaded and read, it is different from what was read after downloading the same firmware using Roborun DFU Loader (I have attached both files).
That makes me believe that you are correct about using dfu-util for DfuSe devices. I will look into that and try to figure out what I need to do differently.
One interesting thing is that when I query the device with minicom I get the same response. ?FID returns "FID=Roboteq v1.8d SDC2XXX 1/8/2018" for both methods of downloading the firmware, and other commands seem the same.

Hi Gabriel,
I did some testing and it looks like the dfu-util can update the firmware with any of these commands:
To read the firmware you need to specify the memory location:
The first part of that bin file matches the original firmware bin file, with the addition of whatever else was in memory. It would be nice if the dfu-util could trim it to just the firmware that was uploaded to the device originally, but for my purposes (just trying to verify that the firmware is correctly uploaded), I think it is good enough.
I did some testing and it looks like the dfu-util can update the firmware with any of these commands:
dfu-util -D new-firmware.dfu
dfu-util -a 0 -D new-firmware.dfu
dfu-util -a 0 -s 0x800400 -D new-firmware.bin
dfu-util -s 0x800400 -D new-firmware.binTo read the firmware you need to specify the memory location:
dfu-util -s 0x800400 -U read-firmware.binThe first part of that bin file matches the original firmware bin file, with the addition of whatever else was in memory.
