Cannot compile project due to memory overflow in a BC805M

[Quetzacoal]

Hello, I am trying to compile my project to upload it to a BC805M using nrf 52DK

I have uploaded some sample code so I know flashing works

The problem is when I try to build my custom code I can get 2 errors either

1. Error: Image size (0x133c8) + trailer (0x630) exceeds requested size 0x200

or

2. c:/ncs/toolchains/cf2149caf2/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: zephyr\zephyr_pre0.elf section `text' will not fit in region `FLASH'
c:/ncs/toolchains/cf2149caf2/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: region `FLASH' overflowed by 12920 bytes

I have already used this solution but it seems it does not fix the problem. Do you have any suggestion? Thank you

CONFIG_PM_PARTITION_SIZE_MCUBOOT=0x10000

I created a new project with the minimal example and I am able to load the program into the board but now I have a new problem, I will create a new post

Hi

The nRF52805 on the BCM805 module has very limited RAM and Flash memory, and that is what seems to be the issue here. What are you trying to add to the project exactly? Not much more than a simple BLE application will be able to run on this board, and if you want a larger/more complex application, you should check out some of the SoCs with more memory. 

• nRF52805 (for reference): 192 kB flash and 24 kB RAM
• nRF52832: 512 kB flash and 64 kB RAM
• nRF52833: 512 kB flash and 128 kB RAM
• nRF52840: 1 MB flash and 256 kB RAM

Best regards,

Simon

I need an application that controls two leds using a button on an app through bluetooth communication.

I have already purchased an nRF52832 and I will compare with the nRF52805

Thank you

Hi

That application doesn't sound too complicated and should fit on an nRF52805 I think. Are you adding a bootloader in order to be able to do DFU in the future or some other libraries that might be taking a lot of space?

Best regards,

Simon

It looks like the module that is overflowing my memory is CONFIG_BT_PERIPHERAL is it possible to create this program without this module?

I find it incredible that no examples are to be found on how to receive data without this configuration. The only example I found that does not use it is the beacon. That example works fine.
