1.1 Patch IAR Embedded Workbench
TouchGFX ST STM32L4R9 supports IAR Embedded Workbench version 7.8x and 8.11 but these versions needs to be patched to support the STM32L4R9 microcontroller
Download and extract the file EWARM_STM32L4Rx_Support_DualBank_V3.zip into your IAR Embedded Workbench installation typical:
|Version 7.8x||C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.5|
|Version 8.11||C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0|
1.2 Install ST Link Utility
To use TouchGFX for ST STM32L4R9 Disco, you need to install STM32 ST-Link Utility version 22.214.171.124 or newer, which is available from st.com.
The standard implementation for STM32L4R9-Disco uses the ChromeGRC functionality to reduce the size of the framebuffer. This means that SlideTransitions using Animation Storage is not working: The invisible parts of the framebuffer are not saved in RAM and can therefore not be copied to Animation Storage and shown later. Use other moving elements like ScrollingContainer or SwipeContainer to achieve the same effect.
