Reduce Lvgl task priority


i want to reduce the priority of the lvgl tasks, because it is crashing with a realtime ethernet task

What MCU/Processor/Board and compiler are you using?

STM32F746G-DISCO with Mbed online compiler

What LVGL version are you using?


What do you want to achieve?

i want to run the realtime Ethernet on the highest priority and have the lvgl with a lower priority

What have you tried so far?

i tried to increase the cycle times but it didnt make a difference. Adding just a text label with a small font ethernet task and Lvgl task are running both.
By adding a bigger font or even a gauge the system crashes with a Error Message: CMSIS-RTOS error: ISR Queue overflow

Thats the rason i believe that both tasks are running on the highest priority and as the workload to Lvgl gets too much the system crashes.
As i dont want to slow down the real time ethernet Lvgl has to use interrupts with lower priority

It sounds like you’re using an OS; you should look into its documentation for info on how to reduce task priorities.
