Oops - unable to determine board type... model:14

[MWW1977]

Hi there,

I'm trying to get a module for the MagicMirror to run on my Pi 3A+. This involves 2 HR-SC04 sensors and to connect them to the correct pins I want to run

Code: Select all

gpio readall

. BUt on doin g that I get the notification: Oops - unable to determine board type... model:14

I already found similar items when I Googled for it but not with "model: 14" at the end.
Nonetheless I first updated the wiringPi version to 2.46.... with the same notification.
I installed a fresh wiringPi from the Home/Pi location and run "gpio readall" .... still the same result.

When I use: "gpio -v" I get:

Code: Select all

gpio version: 2.46
copyright.....
this is....
For details ....

Raspberry Pi Details:
Type: Unknown14, Revision: 00, Memory: 512MB, Maker: Sony
* Device tree is enabled.
* --> Raspberry Pi 3 Model A Plus Rev 1.0
* This Raspberry Pi supports user-level GPIO acces.

Does anybody knows what I must do?

Possibly wiringpi has not yet been updated to recognise a 3A+.

Possibly wiringpi has not yet been updated to recognise a 3A+.

AAaaaaahhhhh crap! Just my luck!
Okay...then I will swap the sd card from my Pi 3A+ to my 3B+ tomorrow and check it again.
Hope that's the solution. Will report it tomorrow

If you look at https://git.drogon.net/?p=wiringPi;a=co ... 57e9bd533a it's relatively easy to see what changes were made for "PI_MODEL_3P 13". It wouldn't take long to replicate those lines for a PI_MODEL_3AP. It amounts to about five lines of code (including making changes from V2.46 to V2.47).

If the code was on Github, I'd have forked it and done the update for you.

Six lines of code that need to change.

[MWW1977]

in what file should I change this?

The diff for each file that changes starts with +++ followed by the file name.
You can feed that into the patch command. It was created with diff -u.

Go and read the fine man pages.

[CPJ]

Raspberry Pi 3B+ and 3A+ both use BCM2837B0, essentially the same devices, the 3B+ has 1GB RAM, Ethernet and wireless. Both have 17× GPIO, and HAT ID bus

So only small modification is needed to wiringPi, you can do it by hand if you don't want to patch.

• git clone git://git.drogon.net/wiringPi
• cd wiringPi

For future reference just search for all: PI_MODEL_3P using grep, and add matching entry for PI_MODEL_3AP

grep -rni "PI_MODEL_3P" *

gpio/readall.c:308: else if (model == PI_MODEL_3P)
gpio/readall.c:357: (model == PI_MODEL_3) || (model == PI_MODEL_3P) ||
wiringPi/wiringPi.h:102: #define PI_MODEL_3P 13[/color]

Then:


update : wiringPi/wiringPi.h:

Code: Select all

  
  #define PI_MODEL_3AP           14

update : wiringPi/wiringPi.c

Code: Select all

const char *piModelNames [16] =
     // replace -  "Unknown14"  with   "Pi 3A+"

run
./build

Your done.

You shouldn't need to do that stuff. Gordon Henderson has updated the "official" version to V2.48 for RPi3A+.

[Gui Joris]

Thank you, Dougie.

I made the changes as suggested, and all is well.

I could, however, not yet find the 'official' 2.48 version Gordon has updated.
Where is this hidden ???

Have a nice day.

Thanks.

Found, tried and succeeded.
