Memory parameters for nRF51822 Softdevice S130 v1.0.0 vs S130 v2.0.1?

[nar0909]

Hi,

I have been using the following parameters to flash program the example ble_app_uart_c_s130_pca10028 (SDK 9) but the problem is the it uses the S130 v1.0.0 softdevice (Hex size = 302kb)

while the same example from SDK 12.3, uses the S130 v2.0.1 softdevice (Hex size = 298kb).

I'm trying to use the full functionality of the S130 in multirole with UART along with 8 peripheral connections to one central device. So the below are my current flash parameters,

My Target Device: nRF51822 QFAA G1 (also a few G0's)

Step 1: Softdevice: Using STM32 based black magic probe (arm-gcc interface) -> erase the chip -> load the softdevice first.

Here are the differences,

If we use SDK 9, then S130 v1.0.0 start address= 0x0, load size = 109720

If we use SDK 12.3, then  S130 v2.0.1 start address= 0x0, load size = 108448  

Step 2: ST-Link Debugger with ARM Keil,

Options for Target,

IROM1 -> 0x1C000   ,   0x24000

IRAM1 -> 0x20002800  ,  0x1800

RAM for Algorithm,

Start -> 0x20000000   ,   Size -> 0x2000

Programming Algorithm,

nRf51xxx   2M 

Can someone confirm if the above settings are correct for my Target?

At this stage the flash seems to be successful and device functions normally but it is only able to connect to one slave/peripheral device? (SD S130 v1.0.0)

Also is it possible to use SDK 9 example with SD S130 v2.0.1?

Please Advice

Thanks

For new development I would likely recommend you to check out the nRF52-series, such as the nRF52832. The latest SDK supporting the nRF51-series is SDKv12.3.

For a complete list of which SDK and softdevice (SD) versions that work with the nRF51-series please go to:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51/dita/nrf51/compatibility_matrix/nRF51422_nRF51822_ic_rev_sdk_sd_comp_matrix.html?cp=3_0_4

In terms of RAM and code requirements for different softdevice binaries you should download the SDS document in the above table for the specific softdevice you are interested in. I don't recommend to mix SDK and SD from different releases than intended from the above table, due to API dependencies in many SDK modules.

Hi Kenneth,

Thanks for sharing the info, but I was wondering if I could use Softdevice S130 v2.0.1 with an SDK 9 example?

Yes, I'm aware the mapping states it uses a S130 v1 for SDK 9 but just assuming it would just be some additional bug fixes in the v2.0.1 so will it still work if I use the latest SD S130 for SDK 9?

Please let me know if its completely different from S130 v1

Thanks

Hi Nar, if you download the zip file for S130v2.0.1 there is also a migration document that describe the work involved.

Thanks Kenneth, appreciate your response.

Yes you were right. It solves my puzzle.
