bootloader firmware size issue - wonder if it's okey

[Jeong Hyun Seok]

I'm developing custom board of nrF51822 CEAA (256k, 16k)

I set my bootloader ROM, RAM just like below

as I understand,

• Firmware size should not larger than 0x3C00 = 15360(decimal)
• RAM should not larger than 0x1380 + 0x80 = 0x1400 = 5120(decimal)

but when I compile my bootloader program, size result is below

so, firmware = code+RO+RW = 14692+1532+340 = 16564 (Exceed!!) RAM = RW+ZI = 340+4232= 4572

As you know, address 0x3FC00, we use 1 byte for BANK_VALID_APP I think firmware size is exceeded, It might be a problem.

Please check, if there's any problem or need to fix things when ROM for RAM size is exceeded.

FYI, DFU works fine though

Here I attach .map file.

1. As I see the map. maybe compression is working?

2. So, if I set attribute((used)), keil prevent that memory area, eh? Where could I get more information, or (if possible) visual description for bootloader and bootloader settings location.

Thanks in advance.
