Posted on May 11, 2015 at 05:18Dear sir: I use STM32F407 discovery board's ST-link feature to communicate with my custom STM32F427 board. I can download (and reset/run) the execution file created by uVision 5.0.5 via ST-link utility tool. However uV...
Posted on June 19, 2015 at 13:27Hello, what is a sensible relation between the GPIO speed setting and peripheral device speed? E.g. OSPEED = 00 on a >2.7 Volt STM32F42x with 10 pF load has a value of 8 MHz max. Is that good for a SPI clock rate of 8...
Posted on June 06, 2015 at 15:17HelloThere is some mismatch between recommended power supply scheme of stm32f407(page 76 of stm32f407 datasheet, Rev5) and what is implemented in stm32f4discovery.It would be good to be explained by someone from ST.
Posted on June 18, 2015 at 13:29Hello everybody,I use a SD card (SDIO). - When the SD card is inserted but not mounted, my analog inputs convert voltages with a very good precision.- When I mount the SD card, my analog inputs starts to convert volta...
Posted on June 15, 2015 at 10:20Hi,I noticed that when i'm trying to flash via the ST-Link_CLI in win 7 when i'm administrator.the response that i'm getting from the ST-Link_CLI is ''Unable to open file!''but when i'm doing it without setting my se...

Posted on June 18, 2015 at 22:06Hi, I have been trying to run critical interrupt routines from ccmram with gcc toolchain following the instructions in http://www.st.com/web/en/resource/technical/document/application_note/DM00083249.pdfI think I have...
Posted on June 18, 2015 at 16:54In one project there is a large rotating machine. It would help a lot if programs could be uploaded wirelessly(, while the motor is on). We would like to do other things, so doing our own solution is not good idea. It...
Posted on January 10, 2014 at 04:14Working on STM32F051. The bootloader works fine but the interrupt vectors in application file doesn't work even after locating vector table to SRAM. Any solution will be appreciated.
Posted on June 18, 2015 at 11:41Hello,I have written own bootloader/IAP that should start next firmware (jump to it).It is working very well, but when the firmware is loaded, then interrupts are not working.Of course I have configured:#define VECT_T...
