RW memory range over lap problem when compiling for nrf52840

[Mitch996]

Hello, I got this error:

Error: L6221E: Execution region RW_IRAM1 with Execution range [0x20003120,0x200046a8) overlaps with Execution region ER$$.ARM.__AT_0x20003000 with Execution range [0x20003000,0x20003800).

I assume ER$$.ARM is something CM4 related that better left unchanged , but I duplicated the RW_IRAM1 settings from an example project by nordicsemi.

The thing is, I wanna be 100% sure about what I'm doing so I'm not going to straight up modify the IRAM1 range in the "magic wand" setup into something less overlap-ish.

So what can and should I do?

What settings are you using? Which SoftDevice version are you using?

Hello Petter Myhre,thank you for your attention. Here are screencaps of the settings that I'm using: https://ibb.co/c2x3oF https://ibb.co/hQAZvv https://ibb.co/dCA1av https://ibb.co/bvpG8F

I didn't know exactly all the parameters so I duplicated them off from an example project by nordic. I duplicated them as faithfully as possible.

I'm using the softdevice s140.

I'm not sure why it says Options for Target 'nrf52822 xxAA' in your picture, but ok. What version of the S140 are you using? It will decide if your IROM1 start is correct or not.

Anyhow the IROM1 size is incorrect. It should be 0x100000-0x24000 = 0xDC000.

What if you try to use 0x20002620 for IRAM1 start and 0x3D9E0 for size?

I also see that you have 0x4000 in RAM for Algorithm size (0x2000 normal). Reset and Run is also unchecked (normally checked). Not that these should matter on compilation.

Hi Petter Myhre , thank you for the fast reply, the target is nrf52840 without a problem, MS snipping tool for some reason won't capture highlighted items.

I'm using s140_nrf52840_5.0.0-3.alpha_release, if that's what you are asking, the latest version I downloaded last week.

I'll try the start address and range, will get back to you soon.

Hi again Petter Myhre, your address range worked! Would you be so kind as to tell me what it was all about?

Edit: By that I mean how did you calculated the proper address and range?
