Update this code for use with a 16Gb Raspberry Pi 5?

[AlistairS12]

I have been using this excellent code to control a couple of SPI OLED displays on a Pi4 for a long while, and have now upgraded my system to a Raspberry Pi 5 with 16Gb of memory. And the app does not run anymore. I get:-

�[6n�[H�[m�[31m2025-04-14 22:24:37 ERR RPI_hal: not running on supported rpi HW
�[mNo spi, stopping

I am not a bad programmer and could under take the changes myself, I would need a few pointers as to where to look for info.

Having stepped through the code in Lazarus, the result of AnalyzeRevCode is

'rev1.1;0x06;0x17;0x04;e04171;40;4;aarch64;Sony UK;0x00'

0x06 os 16GB, and the 0x04 is the BCM2712 processor. As to what the RPI_bType of 23 ($17) is, I have not worked out just yet.

Help or this being updated would be appreciated.

Best regards,

Alistair.

Hi AlistairS12, rpi5 is not supported. I tried to support it, but the changes to support the new GPIO chip are very massive. I couldn't get information, to access the peripheral base for the new BCM2712 processor. The function RPI_mmap_get_info modus 7 checks, which processors can be supported. You can add the rpi5 processor for testing spi functionality. But gpio is not supported. pls. modify the code in the latest published version and enable BCM2712. so the return valu gets 1.

7 : if ((RPI_mmap_get_info(5)=1) and ((RPI_hw=BCM2708_c) or (RPI_hw=BCM2835_c) or // new in Linux raspberrypi 4.9.11-v7+ #971 SMP Mon Feb 20 20:44:55 GMT 2017 armv7l GNU/Linux (RPI_hw=BCM2836_c) or (RPI_hw=BCM2837_c) or (RPI_hw=BCM2711_c) or // rpi4 // (RPI_hw=BCM2712_c) or // rpi5 not supported (RPI_hw=BCM2709_c))) then valu:=1; // runs on known rpi HW

Hi rudiratlos, thank you for your quick reply.

It is a shame that it is not easy.

I have been using your code for ic2 projects as well!

The reason I have been using Lazarus to program is that I use Delphi in my job and yes I could do these things in Python, but, I'm not a young person and swapping between languages is getting harder.
