Developing for nRF52810 - the full story?

[awneil]

nRF5 SDK > nRF5 SDK v15.0.0 > User Guides > Developing for nRF52810 gives a list of things to do to adapt an nRF52832 project to an nRF52810 target.

But, looking at the SDK v15.0.0 PCA10040 (nRF52832) and PCA10040e (nRF52810) blinky example, there are a few extra  changes which are not mentioned; viz,

• Change FLOAT_ABI_HARD to FLOAT_ABI_SOFT
• Change __HEAP_SIZE=8192  to 2048
• Change __STACK_SIZE=8192 to 2048

Are these essential, or just optional?

Are there any others?

EDIT

Please see updates below if the link doesn't work ...

There are some hardware differences; eg, see: https://devzone.nordicsemi.com/f/nordic-q-a/45002/does-nrf52dk-emulation-of-nrf52810-support-non-fpu-environment/176916#176916

The link in the original post and its DocLib replacement no longer work!

Try this:

https://devzone.nordicsemi.com/f/nordic-q-a/48253/request-a-link-to-the-nrf52810-proting-guide/191295#191295

Although the OP link was broken, the navigation is still the same:

And a heads-up that there is currently no Gazell library for devices without FPU (nRF52810 & 52811):

I am using IAR compiler with nRF5_SDK_14.0.0_3bcc1f7. I get the same error. I searched for FLOAT_ABI_HARD in all the .h and.c files, but it can't find it.

Below is the compilation error.. Thanks..
