error: L6236E: No section matches selector - no section to be FIRST/LAST.

Question

Hello, 
 I am working with nRF52832 and using Keil uVISION 5. 
 While building the exapmple from nRF SDK v15, I am getting this error : 
 error: L6236E: No section matches selector - no section to be FIRST/LAST. 
 
 I also tried the following suggested on ARM forum, but the error remains same. 
 
 I opened the project in keil. 
 In target->linker , I unchecked Use memory layout from target dialogue. 
 Entered 0x00026000 in R/O base and 0x200018A8 in R/W base address from .sct file in \..\components\softdevice\s132\hex\s132_nrf52_6.0.0_softdevice.sct

******File content******** 
 
 ; ************************************************************* ; *** Scatter-Loading Description File generated by uVision *** ; ************************************************************* LR_IROM1 0x00026000 0x0005A000 { ; load region size_region ER_IROM1 0x00026000 0x0005A000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) } RW_IRAM1 0x200018A8 0x0000E758 { ; RW data .ANY (+RW +ZI) } } 
 Any help?

Hi, 
 Most examples relies heavily on the board support package (BSP) which is an SDK library that relies on a certain number of buttons, leds, etc. to be configured. In order to build the examples for a custom board you should: 
 
 set the preprocessor define BOARD_CUSTOM 
 remove the preprocessor define BOARD_PCA10040 
 in <sdk folder>/components/boards, make a copy of pca10040.h that you name custom_board.h, and change the LED and button defines to reflect your custom board. 
 
 That way you should be able to run most SDK examples directly (unless they need more leds or buttons than are available on your board). 
 Alternatively you must manually go through every place where the board support package or the defines within the board specific board file are used, and change that. Unfortunately I do not have a full overview of all the places that would be, but fixing one error message at a time would be a valid approach.

Hi, 
 I think I finally figured out what may be the issue. In Keil, next to the LOAD button in the toolbar, there is a drop down menu where you can select either "nrf52832_xxaa" or "flash_s132_nrf52_6.0.0_softdevice". 
 The first one, "nrf52832_xxaa" (or correspondingly for other SoCs depending on which project), is for building and programming the application. 
 The second one, "flash_s132_nrf52_6.0.0_softdevice" (or correspondingly for other SoCs), will generate the error messages that you see if you try to build it. It is only intended for loading the SoftDevice onto the SoC. 
 So, in order to build the project correctly you must select the first item, which selects the application. 
 If the SoftDevice hex file has been corrupted by attempting to build a new one, you can find the SoftDevice for download on our web pages. nRF52832 SoftDevices are downloadable from the downloads page for the nRF52 DK .
