I am currently working on http://www.keil.com/appnotes/docs/apnt_268.asp example and stuck at stage 3 and 4. The MC doesn't start GUI thread and when I plug in a USB the os_error is called. How can I solve this? What's wrong?
Dear
I have similar problems with apnt_268.
The code, even the code provided in zip file, go stuck on the "GUI_DispString("Hello World!");" call.
I think it has to do with the SDRAM that is not properly initialized.
Could you already resolve your problem?I'm interested in getting the source code that correctly displays something on the LCD screen.
The SDRAM initialization in the project was not correct.
I used the "system_stm32f4xx.c" out of the example "emWin example (STM32F429I Discovery) to get it working.The "system_stm32f4xx.c" from this example project has an adapted SDRAM initialization, not present in a standard generated project.
