Posted on April 27, 2018 at 09:54Hey guys,i was wondering how to Programm an STM32 using the stlink with a C# Interface.I noticed that the SW4STM32 IDE connected to the st link by searching for a hid device with specified VID and PID.(I'm not lookin...

Hey thx for your reply. I have been looking at the example project.But I still have 2 questions:1) in middlewares/fatfs/drivers/sdram_diskio.c there are 2 functions which seem to be used read/write variables in the external RAM/** * @brief Reads ...

hey thx for your fast answer. The disc board above has an LQFP144 pin package. I know that QuadSPI or Octa SPI is recommended for using external memory. However I ony got this board here, and it should only serve as a proof of conecpt How can I ext...

Posted on July 09, 2018 at 22:38@Turvey.Clive.002I used True Studio to reproduce the error.Looks like I&39m allocating memory from some protected regions.I did track down the problem. The problem is C++ new operator which is probably used internally...

Posted on June 25, 2018 at 23:26hey,the faulty part is that my vector get's larger than the available free heap. The vector probably trys to allocate memory from some protected area.How can i diagnose the hard fault further. There is no stack trace....
