Thanks Aryan, as you said changing iRAM settings made all the example code to work on this board.

Thanks Brajesh

There will be no issues. Just using S130 means it is just BLE, so its a simple use case that the chip nrf51422 will surely fulfill

Aryan, I was referring to your earlier comments and i have a doubt as you mentioned "If your software worked in 51822(BLE only) then it is OK to use 51422(BLE+proprietary stacks)".

Here "proprietary stacks" is some other stack for nRF51422 ?? Cause i have used S130 Softdevice and planning to use same for nrf51422 as well . Any issues ??

Thanks Aryan for the clarification. Will get back to you once i have DK boards with me tomorrow

The blog link you found from Oyvind is a very nice and with correct settings. Regarding the commen from David about the discontinuation of EK. EK stands for Evaluation kit, they contain older revisions and with known Product ANamolies PAN (workaround for which has been implemented in SDK and SD). DK is development kits and there are much fewer PANs in DK. So it is a good thing for you and your code should work fine on DK. If you have any problems running your code, we are always here to help, but i am quite sure that there will be no problems :)

For IRAM Settings : This Link suggests following Settings :

IRAM size(32 kB RAM) - 0x5800

Also i will have to change Device from nRF51822 to nRF51422 in Project Settings, I think that won't have much effect IRam Settings are fine. ?

Thanks Aryan for the detailed explanation. I assume apart from IRAM settings i won't have to change much from my PCA10001 Code to work with PCA10028. Could you please let me know how would I know what are correct RAM addresses for application ? I'm using S130 Softdevice and following are the current IRAM Settings for my Application in PCA10001: IRAM1- Start : 0x20002800 Size: 0x1800 I'm still waiting for PCA10028 to be delivered, once i get I'll start working on it.

Secondly Aryan, My Customer is worried that the nRF51822-EK that we worked on is going to discontinued soon, following are the statements from David (Nordic Guy):

"That Kit has been replaced by the nRF51-DK. The nRF51822-EK has the previous chip revision that will soon be discontinued"

But i think if our code works out on new nrf51-DK(PCA10028) then there is nothing to worry about.

PCA10001 uses the nRF51822-QFAA, PCA10028 uses nRF51422-QFAC, Should be the same XTAL and LFCLK

PCA10001 stopped at IC version2. PCA100028 which is nRF51422-QFAC is the latest chip version with fewer PANS.

If your software worked in 51822(BLE only) then it is OK to use 51422(BLE+proprietary stacks)

You job is to check

If I am not wrong PCA10028 has more RAM (32k instead of 16k in PCA10001), so you need to change the IRAM settings in your project. Flash seems same so IROM values should be same.
Whenever there is a product anomaly, we try to find a workaround for it. The workaround theoretically should also work on newer chips (even though the workaround is not needed as the anomaly is fixed). You can check what PAN has been fixed for your PCA10028 and just check that the workaround does not break anything (most probably they wont).

Other than that I cannot think of anything that should effect the behaviour. Please comeback to this thread and let us know your experience.

PCA10001 has nRF51822 and PCA10028 has nRF51422 both as i have checked, we can use the same code on both these Chipsets.
