Posted on May 17, 2011 at 13:32Hi enke, i'm having similar issues with mixing DMA access and sleep mode. In my case it's on the ethernet controller: everything seem to be ok with the ethernet chip itself, but there is nothing in the DMA buffer in th...
Posted on May 17, 2011 at 13:30I'm not sure exactly what do you mean, but there is a rather explicit diagram of the clock system in the STM32 Reference Manual, figure 11 page 107.
Posted on May 17, 2011 at 13:30Hi everybody, I'm making an small sensor thing on ethernet, it's using multicast UDP packets for communication. The ethernet chip has a hash table filter for multicast packets. So far so good, but I don't see which CRC...
Posted on May 17, 2011 at 13:29Hi everybody, Is there a known issue with the DMA transfers between the ethernet MAC and the main memory while the processor is stopped with the WFI instruction? In my code there is a handler for MAC interrupts that ch...
Posted on May 17, 2011 at 12:41I seem to have different results with a stm32f107 chip. I was expecting what Eric got (0xC704DD7B) but instead the chip returned 0x552d22c8. void foo(void) { CRC->CR = CRC_RESET; /* CRC->DR is now 0xffffffff */ CRC-...
