Board: STM32G474E EVAL /using Demo-STM32G474E EVAL EWARM project IAR/ issue with reading BMP file from SD card and displaying on LCD. While I try displaying the image on Lcd I get "Error Popup resource file missing please update sd card content".

[Rrn.3]

I checked sd card contents and it got the required files with right permissions and formatting. I tried debugging and kStorage_OpenFileDrawPixel() used for checking the file and printing on LCD returns kstorage_ERROR_OPEN. This is demo project with nothing changed and sdcard contents were not modified. Any suggestions on this issue

Hello @Rrn.3​ and welcome to the STM32 Community :)

If the microSD™ card does not contain appropriate icons and pictures for the demonstration, this error content "Error Popup resource file missing please update sd card content" is displayed on the LDC screen.

You will find the errors cases in this UM2583 STM32CubeG4 STM32G474E-EVAL demonstration firmware, and this will help you on your project.

Hope this helps you !
