used to get the beginning of the initialization data in flash, and assign it to “_DataLoad”. The “.bss” section contains all the variables that should be zero-initialized, and the symbols “_BssStart” and “_BssEnd” are set to its beginning and end address, respectively. It is marked with “NOLOAD” as well
location counter to make sure the address is a multiple of 4. The same thing is done right before “_BssEnd” and also at the end of the “.text” section, to make sure that “_BssEnd” and “_DataLoad” are multiples of 4 as well. The only thing left is the actual initialization of the RAM. To do that, change
