Migrating to S110 v8

[Anshul]

In the s110_nrf51_8.0.0_migration-document.pdf, the ROM and RAM start and size for the v7.0.0 and v8.0.0 are specified as follows

1. s110_nrf51_8.0.0 IROM1 - Start - 0x18000 Size - 0x28000 IRAM1 - Start - 0x20002000 Size - 0x2000

2. s110_nrf51822_7.0.0 IROM1 - Start - 0x16000 Size - 0x2A000 IRAM1 - Start - 0x20002000 Size - 0x2000

The size of the soft device in v7 is 88kB and in v8 is 96kB.

Can any confirm if the ROM start and size for v8 are correct? Does the size refer to the actual size of the soft device or is 0x00000 + Start + size of the soft device?

The code that I have ported to SDK v8 with S110 v8 is not working and I kind of have a feeling that the start and the size is not set correctly.

The start address and size are correct. There are other little modifications that are required, see this blog.

I actually made all the changes that are listed in this blog. I followed the migration document and made all the changes, else the code would not even compile.

In that case, only thing left to do is to place breakpoint in the reset function to see if it breaks there and start tracing. I got the SD8 working on rev1 of the chip. There must be something missing. Also trace the softdevince init function. Do you have DFU flashed in previously ?

What do you mean with S110 v8 is not working, does you code start? If you put a breakpoint in Reset_handler function in arm_startup_nrf51.s file and see if your PC(program counter) reaches there, then that means that your settings are working.
