ChibiOS 20.3.x to 21.11.x Migration Success for Gateway

The migration from ChibiOS 20.3.x to the latest stable 21.11.x branch has been completed internally for the gateway. This upgrade adopts RT kernel version 7, with custom backports for Ethernet and RS485 functionality, plus adaptations to the new UART API for modem operations. A successful build is now available for testing.

​Key Migration Steps

• Updated core OHS components to kernel 7 compatibility, addressing API changes in HAL 8.0.0 including SPIv2 drivers and improved STM32 support.
• Backported custom Ethernet and RS485 drivers, leveraging UART driver callbacks for transmission end events essential in half-duplex RS485 setups.
• Modified modem UART integration to align with the new driver model, ensuring reliable communication in IoT gateway scenarios.

Resources and Downloads

•  Forked ChibiOS repository: https://github.com/vysocan/ChibiOS_21.11.x.git – contains the adapted 21.11.x branch for OHS.
•  Test release with binaries: https://github.com/vysocan/OHS_2-gateway/releases/tag/test_ChibiOS_21_11 – ready for download and deployment on STM32F4x7 hardware.

Potential Hiccups and Tips

Fell free to test the new binary and report any bugs through the discord @ #gw-latest

Site Shop not Functional

The ECWID shop platform was transferred to Shopify and the free tear option was removed. It is an end, for now :), for the possibility to buy the hardware directly on my blogger. I'll have to look up a new way to integrate web shop into it.
 

For now you can look and buy on Tindie. It is free, but taking like 8-10% from the purchase. Or directly ping me via Discord or email. 

Old Forum Removal

The old forum has come to an end, and Nabble now gathers only dust.
All past posts have been sent out to users as backups.

From here on, new conversations will take place on Discord.
