We have interfaced CS5532 using SPI which is initialized in continuous conversion mode. We read the ADC count in a task being called every 160 ms. When I add following statements in the task, the ADC count read from CS5532 becomes constant.sprintf(De...

The core registers are as follows :R0 = 0 R1 = 0 R2 = 40005400 R3 = 70000 R12 = 802d8f9 LR = 800a88b PC = 8001ba0 PSR = 100002f- FSR/FAR: CFSR = 10000 HFSR = 40000000 DFSR = 0 AFSR = 0By disassembling the code, I found that the faulty instruction as ...

Hello, I found the solution for this problem. I came to know that the ART sometimes fails when we use highest frequency, 120MHz in my case. I disabled the instruction cache and changed the wait states of data cache from 3 to 4. I have not encountered...

Please note that the actual address of the variable is 0x20000130, but the controller tries to access 0x28000130 as pointed by the BFAR register causing hard fault as 0x28000130 is out of the valid range of RAM addresses. It appears that an extra b...

Hello! I am getting constant ADC value through SPI when I add a debug message using UART on STM32F205 with CMSIS RTOS.

Hello, I am currently working on STM32f205 using Keil uvision. I am getting an undefined instruction fault.

Hello! I am currently working on STM32F205 using Keil uvision. I have been getting an INVPC hard fault repeatedly. So I increased the stack size from 0x400 to 0x800 and set the stack alignment bit in CCR register at power on. This removed the INVPC hard
