Posted on May 19, 2014 at 16:33I am trying to use the ST Flash loader software for download STM32F401 and there is a problem when the software tries to read the address 0x1FFF7A22 (contained flash size) and 0x1FFF7A10 (unique device ID). It seems th...
Posted on September 23, 2012 at 22:17I am having a strange issue. I am using FatFS and I have setup the SPI1 withCS - PB14CK - PA5MISO - PA6MOSI - PA7When I just use the SD card interface, everything works well. I am getting the proper SPI signals a...

Posted on May 14, 2014 at 11:54Hello, I've problem with a clock setting for a MCU. There is some points, which describe it. General: MCU: STM32F207IGT6 Clock: HSE 8Mhz -> PLL 96Mhz Using module: ETH MAC - MII 4-bit mode - 25MHz neededFSMC - synchro ...
Posted on May 18, 2014 at 14:10Hi! (Using the STM32F103RBT6 chip) I've configured TIM2 timer as a prescaler for TIM3 (RM0008 page 386). Timer TIM2 is configured for ETR (RM0008 page 365). So what I've got is a 32bit timer counting pulses on PA0 (suc...
Posted on May 16, 2014 at 16:12Hi everyone, i'm trying to enter bootloader from my application, so i could use STM flash loader tool to upgrade software. Everything is working fine and im entering bootloader, but after i flash with flash loader tool...
Posted on May 18, 2014 at 14:46I am using STM205RBT^ & I have noticed that it does not start executing first instruction sometimes. I am using HSI oscillator & used pll to make 120Mhz. My first line in code is to toggle a pin. Only two possibilities...
