Posted on March 14, 2013 at 20:55Environment is an STM32F205VF on a custom board, but the problem has also appeared on a STM3240G eval board with an STM32F407I. Compiler is GCC 4.6.2 at optimize level O0 for debugging. My application has extensive ...
Posted on May 21, 2013 at 16:55Hi, I'm testing the f4 and the fpu. I have a small fpu test like this:volatile float a=0;volatile float b=.1;int c;for(;;) { GPIOD->ODR^=0x8000; for (c=0;c<100;c++) a=a+b; }So by looking at PD15 ...
Posted on May 16, 2013 at 13:53Hello,I'm using the STM32F4 on the discovery evaluation board.I wrote a simple function that calculates the mean of a vector. When the code is starting to make the summation it goes to HardFault_Handler...Here is the m...
Posted on April 02, 2013 at 16:47I need to put some data permanent in the OTP. But I phase a few problem durring debbug. 1. When try to program it on power up like in the FLASH I get the error can't program address 0x1FFF7800 as it is not a part of ...

Posted on May 20, 2013 at 16:04Hi Folks I have this simple example program that I am modifying and by moving one statement into a while statement it breaks it. I'm working on the STM32F4 Discovery boardHere is the code:- /* =========================...
Posted on May 20, 2013 at 18:12I have an external device that I need to measure it's utilization. I don't need code but I value the discussion and techniques offered. target is STM32F407The external device outputs a pulse. minimum pulse width is...
Posted on May 20, 2013 at 15:39Hi all, I have a DSP function and I want to know how many MIPS does it consume. I have used SYSTICK of STM32F2xx device (max frequency 120 MHz) to measure the number of cycles required and now I want to convert to MIP...
Posted on August 23, 2011 at 21:58Hi all, I am new to programming with the STM32 range and am currently experimenting on the Discovery Board. I have been able to get the basics going such as reading inputs, setting outputs, measuring an ADC on a pi...
Posted on May 20, 2013 at 14:55I'm using an STM32f207 part and looking into the FSMC configuration. As a place to start, I took a look at the initialization code for this component as presented in u-boot. At the start of the u-boot FSMC initializati...
