Hello, (the text of the other thread 'CRC' was incomplete)
I want to calculate the CRC_16 of my memory flash. I have the routins and I know
the way to do it.
I have a especial table to calculate a fast CRC_16, and I need to save it also
in flash. The matter here is that I want to save the CRC value in a specific
location in memory flash.
I declare as a const my table and then in my main I write:
#pragma DATA_SECTION (crc_16_ccitt, "sec_crc")
unsigned int crc_16_ccitt;
Acording the memory map(see below), the variable 'crc_16_ccitt' should
store the CRC value in position 07F44h.
I compile the code but 'crc_16_ccitt' isn't where I want.
Has anybody used de 'pragma' directive?
