does anyone know why do i have STRG_BAK folder created ?

this folder and files under it keep raising in numbers when I plug my sd card in
while i can't connect my FC to MP

@Vkd4U2NtVkZOVg
@adezie well...It's very hard to say It's not a hardware issue,Maybe It's the power issue,Maybe the power is just enough to power the H743, then the SD card start suddenly It's the power is not enough for the H743 and SD card.....It's just my guess, It's really depend your hardware design, Maybe you can share you schematic, I can take a look for that.

@Vkd4U2NtVkZOVg here's my PCB design for sd card pinout
Vkd4U2NtVkZOVg
@Vkd4U2NtVkZOVg
@adezie Which LDO did you use on this board? Have you connect the Card VCC to the MCU's VCC?
adezie
@adezie
@Vkd4U2NtVkZOVg yeah, i've connected the sd card vcc to 3v3
@Vkd4U2NtVkZOVg LDO ? what is that ?
adezie
@adezie
i used sdmmc1 pinout
Vkd4U2NtVkZOVg
@Vkd4U2NtVkZOVg
@adezie Low-dropout regulator, It's a converter that convert the 5V to the 3v3 to power the MCU and SD card.
@Vkd4U2NtVkZOVg i used ams-1117 3.3 for my 3.3 regulator
Vkd4U2NtVkZOVg
@Vkd4U2NtVkZOVg
@adezie AMS-1117 should be fine for this board. Try to add some big cap on the SD VCC.
adezie
@adezie
@Vkd4U2NtVkZOVg ill try, i used 50 pF
Vkd4U2NtVkZOVg
@Vkd4U2NtVkZOVg
@adezie NO.....That is way to small... Try 100uF on the AMS-1117 Vout pin, and on the SD VCC, At least 4.7uF and 100nF

I use a 4.7uf on my board

@Vkd4U2NtVkZOVg
@adezie and the PCB is not designed very well...I see you used 4 layer's PCB, So at least put a a whole GND plane on the 2nd layer, So you don't have to router the GND, Just put a via connect to the 2nd layer, It will reduce the GND length. And make sure the power wrie go through the decoupling caps first, The caps will reduce lots of noises.

@adezie
just solve this out this morning, actually, change the chip and tweak a bit of code solve it, thankiess @Vkd4U2NtVkZOVg for patiently helping me, best regards
here's working hwdef for me

any help get started

hello everyone, I'd like to make a target for BETAFLIGHT F4 board (actually a 20*20 board from iflight, that just uses the same target). Is there an easy way to port betaflight unified target?

@ukmook
@Repaired_gitlab I have had a look and can’t see one listed, if it has a baro then it shouldn’t be too hard
Alex
@Repaired_gitlab
@ukmook I've read that doc, but I can't find mentioned "f405min" file it the source code. Also, that board doesn't have a baro, I'm planning to use external baro and compass on TX3/RX3 used as I²C
Malcolm Churn
@ukmook
@Repaired_gitlab that’s ok then if you have a look at other hwdef files, something that’s close then you should be able to copy the settings from inav.
Have a look at this hwdef and make some changes to suit your board
I don’t own one so can’t test

@adezie
@Repaired_gitlab you can, just define this

it based on matekF405 configuration file

does anyone have any idea if i want to add a new variable to Tlog ?

Hey All! I wanted to try to use a Raspberry Pi (without the navio board) as a flight controller running Ardupilot. I know that ChibiOS works on the Raspberry Pi and I was wondering if it would be possible to have Ardupilot running on the RPi as well. If anybody has any tips or pointers that would be much appreciated

Please guide

This is my customized hwdef.dat file
Looking forward to your help!Thanks!

@adezie
what kind of board did u used ?
pixhawk ? omnibus ? matek ? custom ?

Hi, I've ported Ardupilot to a new board MambaF405. I would need a new device Id for this board, is it the right place to request it ? Thx
