Hi,
I'm now using bcm2835.h library to control SPI and GPIO.
When I run my program, it works fine: both GPIO read/write and SPI read/write work.
However, after a few seconds, it enters a state that is assumed to be a GPIO access error. The screen is filled with GPIO access errors as shown below.
Can you please advise what is wrong?
My environment is as follows.
HW: Raspberry Pi Zero 2 W
OS: Raspberry Pi OS ver 12.6
Library: bcm2835 ver 1.75 https://www.airspayce.com/mikem/bcm2835/index.html
Using function to control:bcm2835_gpio_write(), bcm2835_gpio_lev(), bcm2835_aux_spi_transfernb()
best regards,

You need to post the program that generates the error - or enough of it to see how the GPIO is set up ect.
Also the "errors" don't see to have an error code - is it an error?

To make the code public, the confidential part must be removed. Please wait while I prepare.
I do not know if it is an error. Suddenly this text appears on my console and RPi stops running. My code does not have such a print statement, so I am assuming it is from the library.
Does the library always give an error code when there is an error?

Are you facing the same problem?
I would like to discuss this with you while looking at the source code, but as I already mentioned, my code is confidential, so please share your source code with me.
