@ot0tot anything needed to add this ?

The major issue is the EXT1 pin is not connected, so there is no way to sync the gyro with the PID loop. I have a FC, but have not been able to test the target yet.
If you have a Wing FC, please feel free to test and provide feedback. If any of the devs have a way to validate the PID loop rate performance, that would be great also.

The lack of the interrupt isn't a major issue. The consequence is increased jitter and thus poorer filter performance. Also DMA transfers can’t be initiated ahead of the gyro task being called, so there’s a performance hit. We can live without it, but it would certainly be better with.

• Like to merge this.
• We are aware of limitations but this is board is already in production.
• Limitations won't be a big deal for wings - but we would not accept this for new designs.
• New designs will have to deal with new design requirements and standards we set.

i've tried to flash it, everything seems to be working. except SD card for blackbox (can't select SD card on blackbox tab).

i've tried to add:

#define SDCARD_DETECT_INVERTED
#define USE_SDCARD_SPI
#define SDCARD_SPI_INSTANCE SPI3

replaced #define SDCARD_CS_PIN PC14 with #define SDCARD_SPI_CS_PIN PC14

and removed #define FLASH_SPI_INSTANCE SPI3, #define USE_FLASH, #define USE_FLASH_W25Q128FV

Now i can at least select SD card on blackbox tab, but SD card shows fatal error, reboot to retry on bbx tab with CLI status: SD card: Startup failed (same SD card works on SPEEDEBEEF405V4 on BF and it works for SPEEDYBEEF405_WING target in Inav)

This is Inav target, looks like it's SPI3 and PC14 pin, so it should work unless i missed something:
https://github.com/iNavFlight/inav/tree/master/src/main/target/SPEEDYBEEF405WING

This is what i currently have:
config.h.txt

• tried with SDCARD_DETECT_INVERTED and without - makes no difference.

• The mini board does not seem to have flash, also updated SDC related defines with same results.
• Do we need the SDCARD_DETECT_PIN ?

MINI board also have SD card slot. And it fails to connect to it with the same error.
i thought SDCARD_DETECT_PIN is for auto detecting SD card and switch to FLASH if its not detected?
But i see some targets without FLASH still using it...

[limonspb]

i think these suggestions are correct, but it still doesn't make SD card to work...

Came across this issue: betaflight/betaflight#12958

SD card works in BF 4.2.11, but not in any later versions.

Edit: Speedybee reports 4.3.1 works also, but 4.3.2 does not.

this commit causing issues for this FC sdcard: 87c8847c13d7f759548c2384e400d2bc387b159a
so its this PR: betaflight/betaflight#10705

SD card issue resolved here by @SteveCEvans

[ot0tot]

Since this FC lacks the gyro interrupt connection, should we include a line in the define to limit the PID loop rate to 4kHz or 2kHz?

#define DEFAULT_PID_PROCESS_DENOM 2

Let's limit with 4k first and see how that goes?

[ot0tot]

I think this is good to go now. @limonspb reports tested and everything working properly.

Please review and merge when able.
