Assign Value on STM32

Hi,

I used

uint8_t CSD_Tab[16] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

to initialize an array. But when I use IAR EWARM to watch the content in this array, the value is always unchanged. Any ideas?

Thank you

OK, I just figure it out. I did not allocate the RAM memory for it.

Not quite true.

With  ''uint8_t CSD_Tab[16] '' you did actually allocate that array.

Perhaps you never changed it's contents, or the IAR compiler optimized it out.

Trying to learn both C and microcontrollers at the same time could become difficult and frustrating ...
