Hi Henry

I set it like this, but the display fails, it seems that there is not enough memory.

Erase Failed!
Error: Flash Download failed - "Cortex-M4"

Please note that the nRF52810 is not very well suited as a central device due to its limited RAM and Flash Memory, and only rather basic central applications will be possible to run on the nRF52810. Please check out this user guide on how to transfer nRF52832 projects to nRF52810, although it seems Henry_Chou has got you covered.

Best regards,

Simon

The usage method is the same. I had done different SD for project. Normally, it will not be a big deal. But sometimes the RAM is too large in central application. If the RAM is not enough, you may change the other items.

Oh, thank you.
Can I know how to change only softdevice?
I'd like to change from s112 to s132

Change the device name in your emproject

<project Name="ble_app_uart_pca10040_s132">
<configuration

arm_architecture="v7EM"
arm_core_type="Cortex-M4"

I changed the memory.
I don't know to change to nrf52810 project.

Sure ....Check your .emProject file and setup project option in SES.

I can't show the demo. Because my workstation is not built the SES IDE. But I had done SES before. It's okay.

Is it possible to change it in segger?...

above is keil C project

.emproject (SES)

linker_section_placement_macros="FLASH_PH_START=0x0;FLASH_PH_SIZE=0x80000;RAM_PH_START=0x20000000;RAM_PH_SIZE=0x10000;FLASH_START=0x26000;FLASH_SIZE=0x5a000;RAM_START=0x20002ad8;RAM_SIZE=0xd528"

Here

Or ARM embedded gcc look at .ld file for mapping.

The SD ROM size is almost fixed. That means the ROM start is fixed.

But the RAM is depend on your application ,So that , you may get the RAM start when you run the NRF log message.

I'm a beginner starting this time.
I don't know how to map memory.
May I know how?

ble_central have many examples for PCA10040 (S132).

However, almost examples are nRF52832. You have to modify the project item for nRF52810 and take care the memory mapping.
