and in this case, not even the PWM generation works...

@OscarJGV26

did I calculate those addresses correctly?

iram_base=PRU_ICSS1_base+pru0_iram_offset=0x4B200000+0x00034000=0x4B234000, as in example 3 of page 7362....

ctrl_base=PRU_ICSS1_base+pru0_ctrl_offset=0x4B200000+0x00022000=0x4B222000

i had to rebuild my bbblue, new sd card, used steps as usual from infamant guide, i compiled arduplane on the bbblue itself.....it runs but as soon as I connect with MP i get a ton of these messages on console and then i lose connection.....have to reboot ... I have redone the setup a couple times and same issue....

i have done this many times before, not sure what the deal is....

@juvinski
Disable ins_fassample
irwin riolinus
@irwinr89_twitter
i cant change it via MP as the connection doesnt last long enough, is there a parameter file on the linux side where I can set it?
Vinicius Juvinski
@juvinski
What’s the command line are you using to star ardupilot ?
irwin riolinus
@irwinr89_twitter
./arduplane -C /dev/tty01 -A tcp:192.168.1.115:14550 -B /dev/tty02 -F /dev/tty05
its weird it only happens the minute I connect with MP
irwin riolinus
@irwinr89_twitter
nah, I managed to be quick enough to set INS_FASSAMPLE to 0 and save, but it still doing it
Vinicius Juvinski
@juvinski
could you please try to generate the samples( ./waf examples) and then on the build/examples folder
run the INS_Generic sample to see if the messages will appear ?
irwin riolinus
@irwinr89_twitter
i found this file at "/home/debian/ardupilot/libraries/AP_InertialSensor/examples"
but how do i run it? I changed to executable but does nothing
Vinicius Juvinski
@juvinski
you need to compile
./waf examples
irwin riolinus

seems be working, i was moving it around on that screenshot
Vinicius Juvinski
@juvinski
there is a discussion on the ardupilot forum
Safi Amir
@safinwb
is it external imu or onboard ?
if external make sure ur wiring is okay
irwin riolinus
@irwinr89_twitter
no sorry this is a bbblue, all internal..ill check out the link
Vinicius Juvinski
@juvinski
In true, reading the thread this error is related to problems with the sensor, but on previous versions this didn’t happen, there is a change on the way the ardupilot is reading the imu, using an older version like 4, 4.1 I believe you will not have this errors
irwin riolinus
@irwinr89_twitter
ya thats exactly what am doing right now, compiling 4.1!
Vinicius Juvinski
@juvinski
I checked the code and the post, and beside the message is temp (temperature) and what is trowing the message is a temperature reading, according the explanation, this temp reading is just a way to check if the fifo from the imu is ok
irwin riolinus
@irwinr89_twitter
ok its working on 4.1....doesnt lock up...it prints one statement of temp reset, not a nonstop scroll of them like 4.2

@irwinr89_twitter
does the FrSky OpenTX telemetry (Serial opt 10) work on BB? I thought I read that it wasnt supported
Vinicius Juvinski
@juvinski
I believe the main question is the inverted signal of the frsky telemetry
SERIALx_OPTIONS =160 (enable pull-up/pull-downs on TX and RX pins for those external inverter circuits that may require it)
irwin riolinus
@irwinr89_twitter
am using the Yaapu telemetry kit, i believe has inverter in it https://www.amazon.com/gp/product/B07KJFWTCB/
Vinicius Juvinski
@juvinski
So you just need to connect on one of serial ports (4 or 5) and set the correct baudrate and function, should work
irwin riolinus
@irwinr89_twitter
so am confused about Serial4....the bblue schec only shows physical ports for UART0, 1 and 5 (am using UART5 for Frsky Telem but no data so far)
where is 4?
i also cant get the airspeed sensor to work on I2C port, this is first time am running plane on bbblue
irwin riolinus
@irwinr89_twitter
image.png
i have I2C defined on uenv.txt
Vinicius Juvinski
@juvinski
The airspeed configuration is done in the parameter
You must select the digital option and on pin if I not wrong 64 or 65
Don’t need to change nothing in the code
irwin riolinus
@irwinr89_twitter
so i comment this line on uEnv.txt ?? --> dtb_overlay=/lib/firmware/BB-I2C1-00A0.dtbo
irwin riolinus
@irwinr89_twitter
pin 65 didnt work, pin 64 must be conflicting with IMU because horizon is all over the place with that one and speed is supersonic!
Vinicius Juvinski
@juvinski
No, you need to let the i2c line at uEnv
All sensors I vou is using i2c
Imu and baro
What I don’t remember is if the connector available is the same i2c of the baro and imu or if you need to load the i2c2 to enable the second i2c bus to use the board connector
irwin riolinus
@irwinr89_twitter
ill try i2c2
irwin riolinus
@irwinr89_twitter
no good
