ChibiOS Free Embedded RTOS

Proof of concept solution

https://github.com/FOME-Tech/ChibiOS/co ... 4674d910f7

The STM32H7 suffers a silicon bug in the SPI peripheral which results in a garbage byte being read by the peripheral when using DMA.
The ST Errata sheet provides a workaround for this issue in the form of a reset of the peripheral before continuing.

We got a proof of concept fix for the issue below ...

Hello,

Im currently working a on custom H743 board with a Winbond W25Q128 flash IC connected via WSPI with the following pins:

#include "w25q256jv.h"
#include "hal_flash_device.h"
#include "hal_serial_nor.h"
#include "hal_mfs.h"

#define NO_CACHE __attribute__((section(".ram3 ...

I've updated the documentation I've created for LVGL with an example use of delegates.
https://github.com/lvgl/lvgl/blob/dffc2 ... hibios.rst

In fact im seeing a noticable performance increase in using those instead of mutexes.

Hi,

Which is the better way to give this a try? I always wanted to integrate LVGL but never had time...

About the implementation, while considering LVGL I thought that a simpler approach could be to run the whole thing inside a single thread so no synchronization primitives would be required.

In ...

Thank You Edoardo.

The problem was in a old version of ChibiOS in my project. After pulling the latest changes everything works.
I can confirm H743 works fine.

Hello,

I've been scrathing my head to get two fdcan interfaces working simultaneously, from what I've gathered the problem lays in the fact that both interfaces share the same memory area. I've tried spliting them into two 1280 word area's but this doesn't seems to solve the issue.

Any help would ...

Hello,

Im currently playing around with LVGL on ChibiOS, I wanted to ask some professional minds if im adapting the required RTOS functions correctly. I've based my code on the present FreeRTOS implementation in LVGL.

Code below:
/**
* @file lv_chibios.h
*/

#ifndef LV_CHIBIOS_H
#define ...

Problem solved.
The ChibiOS-Contrib driver was missing a bit in the BTCR[0] register that enables the FMC.
Line in question FMC_Bank1_R->BTCR[0] |= FMC_BCR1_FMCEN;

void sdram_lld_start(SDRAMDriver *sdramp, const SDRAMConfig *cfgp)
{
sdramp->sdram->SDCR1 = cfgp->sdcr;
sdramp->sdram->SDTR1 = cfgp ...
