Cannot debug the multillink_central example (s120)

[Kyu]

Hi nordics.

I am trying to do s120 multilink_central example.

However, this example doesn't work well, and I cannot debug central example.

-Environment-

board: nrf51822 DK (6310)

debugger: J-link lite.

sdk version : 6_1

softDevice version: s120_nrf51_2.0.0

--

First, I set the ROM1 start:0x1d000 , size 0x23000
and RAM1 start 0x20002000, size 0x2000 for s120.

and, I set the J-link driver like this....

And I found that I can program this example with nRFgo studio, but i can not download with "download button" in the uvision tool.

When I try to debug this, I get this error message.

How can I solve this problem?

plus) I can download and debug other s110 examples.

You have to update the IROM and IRAM setting for the size of S120. You screen shot seems to indicate that the size is set for use with the S110. The S120 is slightly bigger in both flash and RAM usage. Update these value according to what defined in the S120 softdevice specification.

The error message you see is because you are trying to overwrite the softdevice area from Keil. Because the IROM and IRAM is defined too small for the S120.

Thanks.

I read "s120_nrf51_2.0.0_migration-document" and fix the RAM size up. (start: 0x20002800 size: 0x1800)

But it does not work.

I am using sdk 6_1 and s120_nrf51_2.0.0 with nrf51822 DK.

I didn't change any source code except for ROM and RAM start address and size.

Should I change the RAM for Algorithm tab in the cortex jLink target driver setup??

Did you change the IROM sizes too? They should be start 0x18000 and size 0x27000
