Each line of the partition table is terminated with the bytes 09 0d 0a ("\t\r\n"),
the end of the partition table is marked with a zero byte.
The firmware image must contain at least the partition-table and support-list partitions
to be accepted. There aren't any alignment constraints for the image partitions.
The partition-table partition contains the actual flash layout; partitions
from the image partition table are mapped to the corresponding flash partitions during
the firmware upgrade. The support-list partition contains a list of devices supported by
the firmware image.
The base offsets in the firmware partition table are relative to the end
of the vendor information block, so the partition-table partition will
actually start at offset 0x1814 of the image.
I think partition-table must be the first partition in the firmware image.

Information about STM32F0, STM32F2, STM32F3, STM32F4, STM32F7, STM32L0, STM32L1, STM32L4:
BCD format is used to store the date in the RTC. The year is store on 2 * 4 bits.
Because the first year is reserved to see if the RTC is init, the supposed range is 01-99.
1st point is to cover the standard range from 1970 to 2038 (limited by the 32 bits of time_t).
2nd point is to keep the year 1970 and the leap years synchronized.
So by moving it 68 years forward from 1970, it become 1969-2067 which include 1970-2038.
68 is also a multiple of 4 so it let the leap year synchronized.
Information about STM32F1:
32bit register is used (no BCD format) for the seconds.
For date, there is no specific register, only a software structure.
It is then not a problem to not use shifts.

/*Exercise 3 - Repetition
Write a C program to calculate the sum of the numbers from 1 to n.
Where n is a keyboard input.
e.g.
n -> 100
sum = 1+2+3+....+ 99+100 = 5050
n -> 1-
sum = 1+2+3+...+10 = 55 */
#include <stdio.h>
int main(void)
{
int n, i = 0; //variable declaration
int total = 0;
printf("Enter a Value for n :-"); //prompt
scanf("%d", &n); //getting user input and store
for( i = 0; i <= n; ++i) //checking condition
{
total += i; //calculating the total
}
printf("%d",total); //display total
return 0;
