Posted on August 03, 2016 at 18:29Calls to the HAL_CRC_Calculate are causing hard faults.
When I step through I found out why:
switch (hcrc->InputDataFormat)
{
case CRC_INPUTDATA_FORMAT_WORDS:
/* Enter 32-bit input data to the CRC calculator */
for(index = 0U; index < BufferLength; index++)
{
hcrc->Instance->DR = pBuffer[index]; <--- this instruction
}
temp = hcrc->Instance->DR;
break;
At the marked instruction, the hcrc handle becomes corrupt. The Instance pointer (instead of DR) gets assigned the value of pBuffer[index].
Eventually the entire hcrc handle is completely corrupt, and this causes the hard fault.
The code looks sound, why is this happening?
Anyone have any ideas?
