Problem while programming with Algo builder

[CDent.1]

Hi,

I use Algo Builder to test the sensortile.box, but I can't program the board using the algobuilder software (after I have compiled) in order to test the functionality, even if it seems to be possible to program the microprocessor using directly the STM32CubeProgrammer, and the driver in the device manager seems to be correct.

Can anybody help me? Thanks,

Cristian

Hi,

did you try the Option 1 or Option 2 to enter the SensorTile.box to DFU mode?

Option 3 will be available as soon as the AlgoBuilder firmware will be programmed for the first time, because it requires direct support in the firmware.

Dear Miroslav,

I Tried for sure Option 1.

I'm not sure if I have tried even option 2 since I'm not sure which is the Reset Button.

There are 3 button (PWR, BOOT and USER). If the Reset Button is the one indicated as PWR, yes, I have tried even option 2 with the same results

Thanks,

Cristian

Hi Cristian,

actually the SensorTile.box doesn't have the Reset button, you would need to add it manually which is kind of tricky.

Anyway the Option 1 should work as well.

If you do the procedure for Option 1 without opening the DFU window in AlgoBuilder you should see STM32 BOOTLOADER in Windows Device Manager. Then when you open the DFU window the programming should start automatically.

Another option is to find the generated binary file by AlgoBuilder program your SensorTile.box with this binary using STM32CubeProgrammer and since then the Option 3 in AlgoBuilder should be available.

Hi Miroslav,

As you can see from the images there is STM32 Bootloader in Device manager and the STM32CubeProgrammer works.

But The DFU windows doesn't start. Under Option3 should appear COMXX (in the webinar I saw this) but is void

I can try to find the file generated file, but is it possible to make it work?

Thanks,

Cristian

The COMXX appears as soon as a COM port is available in your system. When the SensorTile.box is programmed with a AlgoBuilder firmware, it will expose a COM port and then it should be possible to use Option 3.

Just to be sure, did you successfully build the AlgoBuidler firmware so a binary is available?

[CDent.1]

Yes. It compile, but don't program.

Hi Cristian,

the problem is in detection if any device in DFU mode is available. Friendly name of device instance is used for this purpose.

The string "STM32 BOOTLOADER" is expected but "STM32 Bootloader" is received in your case.

This issue will be fixed in next application release.

Best Regards,

Hi Cristian,

another possibility is to run Registry editor as administrator and search HKEY_LOCAL_MACHINE\SYSTEM key for "STM32 Bootloader" string (check all in Look at).

If value name is FriendlyName change its value to "STM32 BOOTLOADER". Repeat this operation for all occurrences. The device should be disconnected when values are changed. Then connect the device in DFU mode and program the device.

Best Regards,

Hi Marian,

I run regedit as administrator, but I didn't find a "Friendly Name" under the (USB VID and PID). It's written as "Device Description" and there is "@oem89.inf,%devicename%;STM32 Bootloader" but i'm not allowed to change it. A message appears that says that I can't modify it, Error Writing the new content (I changed only STM32 Bottoloader in STM32 BOOTLOADER). See the attached file to understand the problem

I use windows 7 with 64 bits.

You told me that it's possibile to reload a new driver (probably more update). Should I disintall STM32 Programmer and download and reinstall a new one? Otherwaise where can I find a update driver?

Thanks,

Cristian
