SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

L152 discovery board and LCD DisplayString enables bars

just getting my feet wet with a L152 discovery board. Utilizing the LCD I ran into an issue.
Every time I write a String to LCD. (using BSP_LCD_GLASS_DisplayString() ) I end up having the 4 LCD bars being displayed. Had to add BSP_LCD_GLASS_ClearBar( 0x0f ) to clear’em. Kinda works but the bars still fliicker.

Is this a bug in the low level function or do I do something wrong?
How can this be avoided?

mk

guess found the answer myself. the lcd bar segment can be contol the following way:

extern uint8_t LCDBar;
LCDBar = n; n = 0...4
