Need help converting a BF3.1.5 compatible target (fw dump) to current version

[Guili123]

Currently I try to convert the Uvify Draco-Betaflight 3.1.5 Fork firmware to a normal Betaflight Unified target. I am following the Guide and no big issue so far. But I noticed some differences in other unified targets compared to the dumps I have from 3.1.5. There are no DMA or timer entries, I am wondering if there were differences how this works in Bf3.1.5 and if this becomes an issue with the new unified targets if these entries are missing. Is there any way to export DMA und Timer entries with the Uvify (Betaflight 3.1.5) configurator? Any other way to reverse engineer this?

A diff only shows the differences from a unified target (+config) it's build on. A dump shows all settings.

[jflyper]

You should be able to convert basic timer and DMA assignments from target specific target.c and target.h.

And yes, your new unified target needs these settings, otherwise the target will not be able to use ANY timer nor DMA.

I already did a full dump from the Uvify Draco also and the timer+dma information`s are missing in 3.1.5

To clarify this: I have only the dump available. I have no access to the Uvify version from target.c and target.h The source code for the Uvify fork is not available. It is a shame to be stuck on a 3.1.5 fork of betaflight, because the hardware is excellent.

resource show all Unfortanetly: resource show all Invalid

This is the log output from the configurator: -- You need to upgrade your firmware to the latest version of Betaflight before you can use the Status tab. -- Serial port successfully opened with ID: 9 -- Running - OS: Windows, Chrome: 91.0.4472.124, Configurator: 4.0.3 -- Serial port successfully opened with ID: 7 -- Welcome Draco -- MultiWii API version received - 1.32.0 -- Flight controller info, identifier: BTFL, version: 3.1.5 -- Running firmware released on: Feb 13 2018 09:46:38 -- Board: UVF4, version: 12 -- Unique device ID received - 0x5400313236510a36363331

I can`t access this with the current version of the Betaflight Configurator, because the new version commplains that the MultiWii API need to be upgraded.

No entries about DMA and Timer.

To clarify this: I have only the dump available. I have no access to the Uvify version from target.c and target.h The source code for the Uvify fork is not available.

In that case, you have to start with MOTOR and LED_STRIP and guess what target.c looked like for timer and DMA assignments.

Look into appropriate STM32F4 data sheet, mark pins for motors and led_strip. Look at available TIMx_CHy entries that you can assign to those pins.

For example, PE9, PE11, PE13 and PE14 can be assigned to TIM1, CH1 through CH4 respectively. Likewise, PA3 has TIM5_CH4. Then, for DMA, you have to look into corresponding F4 reference manual, DMA request mapping section. If you can find non-overlapping assignments of DMA streams in that table for TIM1_CH1, TIM1_CH2, TIM1_CH3, TIM1_CH4 and TIM5_CH4, then you are done. If not, you have to start over again.

Good luck.

[Guili123]

Thanks, for the hints. So to summarize, this Uvify configurator version, should be able to list timer and dma.

I don't think so. I forgot the exact version, but full timer and dma listing became available much later, probably around 4.0 and later. You can try something like timer show and dma show or just timer and dma to find out on 3.5.x.

[mikeller]

@Guili123: I suspect that you are looking at an uphill battle here - even if you manage to figure out the timers and DMA, 3.1.5 is so old that most pins for other functions like SPI buses, LED, ADC are not configurable, and won't show in a dump (maybe easiest if you provide one here and we can see). So it will require A LOT of guesswork and trial and error to figure out a target for this.

[Guili123]

@mikeller I really appreciate you response here. At least LED is in the dump... Not sure if the flight controller is a F745 or F765

Here is a dump:
