Posted on February 04, 2015 at 07:47 Hello, we have a small software (bootloader) running on a STM32F103. In a new project, we selecte a ''smaller'' type the STM32F105 with less pins. In the bootloader we set a push pull port high. On the new contro...

Thank you for your answers.We have the code already running on F1 and F2 derivates so this problem was unexpected.I did not expect trouble with that feature - lesson learnded ;-)Leo

Posted on May 17, 2011 at 14:13I got a solution by KEIL support which works unsigned long bf; #define BITBAND_SRAM(a,b) ((SRAM_BB_BASE + (a-SRAM_BASE)*32 + (b*4))) #define _bf0 *((volatile unsigned int *)(BITBAND_SRAM((unsigned long)(unsigned char*...

Posted on May 17, 2011 at 14:07have you read the http://www.st.com/stonline/products/literature/an/13588.pdf? This is a complete example of a bootloader unsing the USART.

Posted on May 17, 2011 at 14:07I finally found an example in the FW-library-examples: PWM-Input. This is very close to the problem.
