Could you debug the bootloader and see if you enter main() of the bootloader?

I noticed that:

Usage	Memory range nRF51 (S130 v2.0.x)	Memory range nRF52 (S132 v3.0.x)
Bootloader settings	0x0003 FC00 - 0x0004 0000 (1 kB)	0x0007 F000 - 0x0008 0000 (4 kB)
MBR parameter storage	n/a	0x0007 E000 - 0x0007 F000 (4 kB)
Bootloader	0x0003 AC00 - 0x0003 FC00 (20 kB)	0x0007 8000 - 0x0007 E000 (24 kB)
Application area (incl. free space)	0x0001 B000 - 0x0003 AC00 (127 kB)	0x0001 F000 - 0x0007 8000 (356 kB)
SoftDevice	0x0000 1000 - 0x0001 B000 (104 kB)	0x0000 1000 - 0x0001 F000 (120 kB)
Master Boot Record (MBR)	0x0000 0000 - 0x0000 1000 (4 kB)	0x0000 0000 - 0x0000 1000 (4 kB)

The chip only has 256K ; so application area is 0x0001 B000 - 0x0003 AC00 (127 kB ), it should begin 0x0001 B000 size is: 0x1FC00 then:

0x0001 B000 + 0x1FC00 = 0x0003 AC00 .

but after that it also cannot work , is it the ram I should change ? Any one can give me some tips ? There are 4 services in my project .

Sorry for the late reply . Iusing the 51822QFAA chip , the sdk is 12.03 .

The bootloader setting :0x3AC00 0x5000 / 0x200025E0 0x1A20

application setting :0x1B000 0x1FC00 / 0x20002138 0xDEC8

After download the application it works ok . but after download the bootloader it cannot work .(It cannot search by phone).

Add the Arguments to bootloader software and download by keil , it tell a error messsage:

Reading flash area to program to guarantee it is erased.
ERROR: The area to write is not erased.

Here is my operation step:

1. Eras the chip by nRFgo studio.

2. Using the nRFgo studio to download softDevice and application . (It can find by phone)

3. Using bootloader_secure project to download bootloader.(Tells the error message , if using nRFgo studio to download it cannot find by phone )

Looks like you are missing a dash '-' in the argument, should be -f NRF51. Can you read out the UICR.NRFFW[0] register?

> nrfjprog --memrd 0x10001014

I don't use the watchdog . It is the default status .

mdevil39 — Thu, 28 Jun 2018 09:33:03 GMT

Is it the Arguments write : --program "#H" f NRF51 ? But it said :ERROR: An invalid argument was provided. Use --help for a list of valid . I don't know what character instead of f

I has been try to download by nRFgo studio , it is the same .

Do you use watchdog? I use it and forget about it. Was same behavior.

Hi,

FDS/FSTORAGE will place the "application data" below the bootloader (memory layout) provided that the UICR.NRFFW[0] register contains the bootloader's start address. Based on the error I suspect that this register is not being set. Please make sure you're programming the bootloader with the default debugger configuration shown here (omit the "-f NRF52" argument).
