update firmware fail with piTest -f

[imerledragon]

Hello Kunbus!

I have reset a Core 3+ by flashing it with the buster lite image available in the download area.
After setting a MIO in piCtory, saved and reset the driver, I am trying to update the firmware but all I get is "update firmware fail".

Here is the dmsg:

It sounds like the error is related to a missing file

piControl:error: cannot open file /lib/firmware/revpi/fw_00095_001.fwu

This is the content of the revpi firmware directory:

Code: Select all

pi@RevPi57128:/lib/firmware/revpi $ ls
fw_00071_001.fwu  fw_00075_001.fwu  fw_00081_001.fwu  fw_00093_001.fwu  fw_00098_001.fwu  fw_00118_001.fwu

The updater is already the latest version. I tried to uninstall, reboot, reinstall, reboot.

Code: Select all

pi@RevPi57128:/lib/firmware/revpi $ sudo apt install revpi-firmware
Reading package lists... Done

revpi-firmware is already the newest version (1:1.6).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

The module is configured and present:

Code: Select all

pi@RevPi57128:/lib/firmware/revpi $ piTest -d
Found 2 devices:

Address: 0 module type: 95 (0x5f) RevPi Core V1.2
Module is present
     input offset: 117 length: 6
    output offset: 123 length: 5

Address: 31 module type: 118 (0x76) RevPi MIO V1.0
Module is present
     input offset: 0 length: 34
    output offset: 34 length: 27

At this point, I don't know what I am missing and what should be done next.
What has been done on the Core: flashing, update+upgrade (with apt), configuring the module in piCtory, then trying to update the firmware of the module.

Serial console is not enabled (I have checked, it was not after flashing the RevPi). The kern.log is attached to the message.

How can I get the missing file to get it work?

Thank you very much,
Torpi

Hi,

Everything is fine with your system. The latest firmware for the Mio is version 1.0. The error message is a known "error" as the driver tries to find a firmware file for the base device (95 is core), which doesn't exist as the device is running an embedded firmware. This is not a real error and therefore can be ignored safely. We already have a task in our backlog for suppressing this error.
