Look it up:

http://www.keil.com/support/man/docs/armlink/armlink_pge1362065952432.htm

A key part of any porting exercise is a solid understanding of what you're porting - and what you're porting it to!

So you know what Image$$ER_IROM1$$Base is?

RE: Trying to compile DFU bootloader code in segger embedded studio.

Meera Shah — Mon, 10 Jun 2019 11:55:37 GMT

In keil it is

#elif defined (__CC_ARM)
#define BOOTLOADER_START_ADDR (uint32_t)&Image$$ER_IROM1$$Base

RE: Trying to compile DFU bootloader code in segger embedded studio.

awneil — Mon, 10 Jun 2019 11:53:00 GMT

So the other thing is to look at the Keil Project, and see how it gets its Bootloader start address.

Remember: the chip neither knows nor cares what IDE or toolchain you use - it just runs the code that's in the flash.

So, with any porting exercise, the object is to ensure that whatever ends up in flash is equivalent.

When I ported nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\dfu\bootloader_secure project in Segger Embedded studio

#elif defined (__GNUC__)

#define BOOTLOADER_START_ADDR (uint32_t)&__isr_vector.

But when I look into current SDK nRF5_SDK_15.3.0_59ac345\nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10040e_ble\ses

#elif defined(__SES_ARM) <= It will be under this compiler. So no __isr_vector in this when we use SES compiler

#define BOOTLOADER_START_ADDR (CODE_START)

look at a current SDK example, as that will have an SES project - use that to guide you

RE: Trying to compile DFU bootloader code in segger embedded studio.

Meera Shah — Mon, 10 Jun 2019 11:22:34 GMT

Where I need to provide a definition of __isr_vector?

You need to provide a definition of __isr_vector.

Hey I have resolved these 2 errors described below by adding into flash_placement.xml.

undefined reference to `__stop_dfu_trans'
undefined reference to `__start_dfu_trans'

Can you tell me how to resolve undefined reference to `__isr_vector' ? Because I am working in Segger so #define BOOTLOADER_START_ADDR (uint32_t)&__isr_vector this will be activated.

RE: Trying to compile DFU bootloader code in segger embedded studio.

awneil — Fri, 07 Jun 2019 13:26:13 GMT

Do the same as the SDK 15 does.

It's an SES thing - not a Nordic thing.

RE: Trying to compile DFU bootloader code in segger embedded studio.

Meera Shah — Fri, 07 Jun 2019 12:24:28 GMT

Yes there is no SES stuff in 12.3 . Where should I include my flash_placement.xml file in 12.3 SDK in linker from project option.

Not sure what you mean by that - I thought 12.3 didn't have any SES stuff at all ?

RE: Trying to compile DFU bootloader code in segger embedded studio.

Meera Shah — Fri, 07 Jun 2019 12:05:04 GMT

I have uploaded this image of upgraded SDK code. But in my 12.3.0 there is no option in linker of Section placement file.

So there would be no effects of flash_placement.xml. whether I will do changes or not.

bjorn-spockeli — Fri, 07 Jun 2019 11:33:29 GMT

You,re probably missing the bootloaderSettings section in the flash_placement.xml file, take a look at the flash_placement.xml file from this answer.

Best regards

I checked all the linker configurations. Actually flash_placement.xml can resolve this , which I have seen from higher version SDK nRF5_SDK_15.0.0_a53641a(where ready SES project is there) but in this no Section placement File to add flash_placement.xml file.

RE: Trying to compile DFU bootloader code in emwin segger.

awneil — Fri, 07 Jun 2019 10:16:40 GMT

Still no idea where emWin comes into this!

[quote userid="76020" url="~/f/nordic-q-a/48308/trying-to-compile-dfu-bootloader-code-in-emwin-segger/191588"] I ported this project from keil to Segger Embedded Studio.[/quote]

Aha! a key piece of information missing from the OP!

The message you got is from the Linker - so you haven't (quite) ported (all of) the linker configuration correctly.

So look carefully at the Keil linker configuration, and make sure you have that all correct in your SES Project.

It might help to look at a current SDK, as that will have an SES project - use that to guide you.

I am working with Segger Embedded Studio. I am using nRF5_SDK_12.3.0_d7731ad SDK. Yes I could build all the examples except this example nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\dfu\bootloader_secure . I ported this project from keil to Segger Embedded Studio.

RE: Trying to compile DFU bootloader code in emwin segger.

awneil — Fri, 07 Jun 2019 09:59:37 GMT

Where does emWin come into this?

Can you build the unmodified example?

What SDK version are you using?

Are you using the provided SES Project file?
