nRF51822 iRAM and iROM settings for v0.5 S130 SD?

[rapjr]

What are the iROM and iRAM settings for the v0.5 S130 softdevice for the nRF51822?

The S130 softdevice spec sheet provides some clues, but no specific settings.

I've tried: iROM1: 0x20000 0x1F000 iRAM1: 0x20002800 0x1800 which allows me to load an app, but it doesn't run.

RAM for Algorithm is set to: 0x2000000 0x1000.

(incidentally, why do I even have to set iROM and iRAM? Shouldn't they be part of the device pack?)

Edit: format

RAM_R1_BASE is 0x20002800, call stack is 0x600, total ram size is 16KB or 0x4000. So 0x4000 - 0x2800 - 0x600 = 0x1200 for iRAM size. Tried that, no luck, the linker runs out of room when compiling the S130 example program.

iROM1: 0x1C000 0x24000 iRAM1: 0x20002800 0x1800

s130_demo_example works for me on nRF6310 with PCA10005.

Are you working with the s130_demo that is included in the S130 SoftDevice download?

My settings in it are:

IROM1: 0x1C000 0x40000 IRAM1: 0x20002800 0x1800

Edit: 0x40000 is an error, and is actually way outside the memory range, but it is not critical for the example as is.

Anyway, if you want to develop something with this example as a starting point the correct ROM size is 0x40000-0x1C000 = 0x24000, this is without bootloader and device manager.

So the correct settings are:

IROM1: 0x1C000 0x24000

IRAM1: 0x20002800 0x1800

The flash resource requirements in the S130 Specification are incorrect, this will be fixed.

The correct flash values are:

Flash          |   S130 Enabled   |   S130 Disabled
Amount         |   112KB          |   112KB
CODE_R1_BASE   |   0x0001C000     |   0x0001C000

Sorry about any inconvenience this may have caused.

Thanks Petter, those settings worked. The S130 demo is indeed what I'm trying.
