Hello,
I have a problem with my bootloader. At the first launch I write a 64 bit word in flash in 0x8004030. I was able to check with J-Mem to make a dump of the memory and it flash writing OK.
If I read the value at this address in 0x8004030 there is 0xfffffffff.
In assembler I have:ldr r2, [r5, # 0]R5 = 0x8004030and the result in R2 is 0xffffffff wich is wrong.And if I read the value at this address in 0x00004030 there is good value.
why there is not the same value in 0x08004030 when 0x00004030?
Thanks,
Eric
