STM32F7 Bus Fault with address in nowhere-land

Heyho,after having found the PHY problem I can stream some audio via TCP.But when I don't get the data out fast enough (e.g. TCP ACK takes too long so that there would be a buffer overflow), I stop the transfer and send some UART messages.Without hav...

FP-AI-VISION - SDCARD format or not working?

I have the latest FP-AI-VISION-1, the 747i-DISCO and the BCAM board. I can see the image, but cannot storen anything to a SDCARD. I tried an SDCard that is readable in the original 747i-DISCO demo code, so at least the interface and card seem to work...

Resolved! STM32L011E4 ADC input impedance

Hi,the STM32L011E4 has a R_ADC of 1kOhm max according to the datasheet. Does this hold true for standard channels as well, or do standard channels have a higher impedance? The table with R_AIN_max isn't super helpful in this regard as my calculation ...

Resolved! How does the STM32 knows where should the .BSS section be addressed,and what's the range,when the chip startup initially?

How does the STM32 knows where should the .BSS section be addressed,and what's the range,when the chip startup initially? We know that firmware downloaded into the flash contains section information like .text ,.data ect,while .bss section should be ...

Access Null pointer - M4 vs M33

Hello,Code that was compiled for stm32F407 ( core M4) has an bug that accesses null pointer. The assembly code is as follows: STRB  r1, [r0, #0x01]Where r0=0 and r1=0.Although MCU accesses null pointer, it does not enter hard-fault.But, the same c...
