Is there a simple way fix these compile errors please:

What exactly does it report as an error/warning ?

That the printf format doesn't match the type of the variable you're trying to print ? try fixing that

Hi SamJ1, I have nothing to add to your problem - mbed has been deprecated. I'm trying to follow the same book as you, I'm stuck on listing 5.3 on page 92/3. I do not see the desired behaviour - I think the HAL_Delay() function is causing a problem. Did you get any further in the book?

printf("....%ld\n", (long)size);

 Is this simple enough?
