OVI40 F7 Sparrow does not load firmware
« on: 13. March 2021, 14:22:21 »

Greetings to all, I'm Carmine ik2jtu, I bought a 4 "sparrow. This morning I tried to upgrade the firmware of my Sparrow ovi 40 F7, running the power-up maneuver holding the key plus band freezes on the bootloader screen and does not proceed with loading the .bin file from the USB key.
I kindly ask you if I can do something else for the upgrade ...
Many thanks, 73 Carmine ik2jtu

Hi Andreas and thanks for the quick reply, yes I keep the band + button pressed but nothing happens, it freezes and does not load the file.bin from the USB stick.
Thanks and 73 Carmine.

Andreas may not have understood the operations to be done but I also tried keeping the band button pressed - then I release it by keeping only the power button pressed and the screen turns white which is normal but nothing happens ...
do you want me to attach two photos of the two switch-on modes, one with the band + button and the second with the band- button pressed?

ok Andreas done this procedure already many times and nothing happens ...
Then I'll explain how to proceed
1) usb key already inserted in the USB port with the file fw-40sdr (I have the version with F7)
2) I turn on and hold down band- and power on
3) the following wording appears:
OVI 40 F7 Bootloader
Firmware name: fw-40sdr
DFU Update Mode
Keep Power pressed until finish.
Release Band+ to start DFU Mode.
Screen may go white. This is ok.
PC should recognize new USB device.
4) release the band- button
5) the screen goes blank and nothing happens
6) release the power button and the OVI40 turns off
7) I turn on OVI40 again but the firmware is always the same as before

Same thing Andreas, I do the procedure with usb inserted I switch on holding down the band + key and switch on and freezes with the following writing: OVI40 F7 Bootloader Firmaware Name: fw-20sdr
release band- to skip firmaware update ...
I assumed it was an OVI40 from the initial screen at power up where OVI40 F7 Transceiver UHSDR Vers. D2.11.81 appears ...
You say it's not an OVI40?
I bought it from Arthur SP3OSJ

Hi,
a) What causes the Band-/Band+ swap issue on the Sparrow bootloader?
The UHSDR firmware and bootloader for OVI40 UI build run on the Sparrow hardware because it is from the perspective of the hardware control indistinguishable from the OVI40 UI. And that also means that the hardware button are used in the same way.
So why do you have to press Band+ to get Band- in the bootloader? Indistinguishable for the software does not imply identical.
What actually differs is the button labeling on the Sparrow case. I.e. on the hardware button by default used to handle Band- operation, there is the label Band+ on the case and vice versa. Now, why does the button labeled Band+ on the Sparrow (which I said is the hardware button Band- for the UHSDR OVI40 UI firmware) does Band+?
If you look into the configuration menu on your Sparrow, you will find an entry "Band+/- Swap" and it is set to "On". Hence the buttons behave as labeled. So far so good, that is why the button does at advertised on the case.
However, the UHSDR OVI40 bootloader (which is different from the UHSDR OVI40 firmware) does not have access to this configuration information, and for that reason it will use the default arrangement (i.e. Band+/- Swap Off). This difference between label and actual behavior makes the OVI40 bootloader instructions confusing for you. Bootloader always uses the default layout. BTW, Step+ and Step- are swapped as well.
b) As Andreas said, follow the instructions to the letter and following a) treat for the bootloader part button labeled as Band- as Band+ and Band+ as Band-. Now watch the green LED. If it blinks slowly, the bootloader has not recognized your USB drive. Why, I cannot tell. Maybe the power supply, maybe something else. To which of the two USB connectors (top or bottom) the drive is connected to? Bottom is the correct one, the one which is a Micro USB connector on the Sparrow ( on the OVI40 and mcHF this is an USB A host connector and is on the top of the case). The slightly larger MiniUSB connector is used to connect to a PC and for the DFU Upgrade procedure, which you may want to try in case the USB drive is not working.

Hi
One picture is worth more than many sentences.

Hi Arthur, exactly what I did, then I turn on while holding band + button
Unfortunately I don't have a 2 Gb Kingstone datatraveler USB stick
A perhaps trivial question, you can do firmware update in DFU mode?
