Posted on October 17, 2012 at 11:38Due to an error in manufacturing we have a lot of modules with a 32khz resonator with 12.5 pF for low speed external clock and two 27pF aditional capacitor to ground. Prozessor is the STM32F103RCT6. The real time ...

Hi,
I am using the software example 'MassStorage' , the IAR compiler and the STM32F103ZE kickstart board for development.
I wanted to add some functionality which requires consecutives reads from ...
Posted on October 18, 2012 at 10:11Thanks ! What would be a good methode to increase reliability ? I can't exchange the 12.5pF resonator, but I could change the capacitors. ''Knik'' suggests to use 15pF rather than the 27pF - would that influence th...
Posted on September 06, 2012 at 09:08Thanks for your replies. Problem solved. The _SdRead function had code to wait for the DMA to finish - but didn't had the proper flags included. Solution: just add the flags mentioned above. - Cols
Posted on September 05, 2012 at 10:24I looked into the issue a bit deeper: When things start to fail, the SDIO_FLAG_RXACT SDIO_FLAG_RXFIFOHF SDIO_FLAG_RXDAVLFlags are set, when everything is fine, the SDIO_FLAG_CMDREND SDIO_FLA...
