Why the support to little LVGL has been downgrade to 6.1.1 when in SDK 2.8.2 was 7.0.0?

[mperez1]

Hello there,

I'm struggling trying to develop a graphic application with the LVGL, and for my surprise when I updated the SDK to the new version the library version has been downgraded. So now the new examples are not running in FreeRTOS and are not using the gpu hal developed for nxp (littlelvgl/lvgl/src/lv_gpu). Why this happen? Will be there any attempt in the future releases of the SDK to use the new versions?

There is any tip in order to improve the performance of this library with the hardware of the imxrt1050?

Thanks,

Miguel

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Why this happen? Will be there any attempt in the future releases of the SDK to use the new versions?
-- Yes, it will use the updated version of little LVGL in the future release of the SDK.
2) There is any tip in order to improve the performance of this library with the hardware of the imxrt1050?
-- In my experience, it can benefit improve the code executing performance by remapping the code to the TCM area to run, especially for crucial code.
In further, the DMA engine also is able to improve the LCD performance.

Have a great day,
TIC
