InsufficientResources response code while performing USB DFU

[Nabeel Ar]

I've mistakenly closed the case https://devzone.nordicsemi.com/f/nordic-q-a/85450/insufficientresources-error-message-while-performing-usb-dfu?ReplyFilter=Answers&ReplySortBy=Answers&ReplySortOrder=Descending and didn't find any solution. 

Board: NRF52833 (PCA10100)

SDK version: 17.0.2

Softdevice: S122

I am trying to perform USB DFU for my application. As I am using nrf52833 board, there is no available bootloader for USB in the SDK. So I've changed The Build configurations and linker settings of PCA10100e USB bootloader to PCA10100 board. While performing usb dfu using nrfutil I am getting InsufficientResources error message. I understood that this error message has something to do with insufficient Memory, So I've tried to flash a blink program using USB dfu which works fine. 

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x80000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x20000

FLASH_START=0x33000

FLASH_SIZE=0x20000

RAM_START=0x20000008

RAM_SIZE=0x1fff8

This is the section placement macro of the usb bootloader.

These addresses work fine for Blink program (small file) and not for my application (large file).

How can I solve this issue? Thanks in advance

Hi, 

You could try to modify the start address. See Memory layout. If setting 0x78000 for flash start address would cause the error, please upload the project. 

You also could check the setting of PCA10100e (See the Development kit for nRF52820) to rever to PCA10100.

Amanda

I've changed everything according to this https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52820_dev_kit.html?cp=4_3_4 still I get the error message

what addresses should I have to add to these two properties?

Debug > Simulator > Memory Simulation Parameter

Code > Linker > Memory Segments

[Amanda Hsieh]

Hi, 

It's Code > Linker > Memory Segments. You can refer to the setting of the pca10100_s113 bootloader.

Hi Amanda, your instructions are not clear to me. I updated the pca10100_s113 address configurations to project. 

FLASH_PH_START=0x0
FLASH_PH_SIZE=0x80000
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x20000
FLASH_START=0x78000
FLASH_SIZE=0x6000
RAM_START=0x20002ae8
RAM_SIZE=0x1d518

above are my address configurations. They are same as the example project you suggested.

I still face the below issue. 

section .tdata overlaps absolute placed section .mbr_params_page
section .mbr_params_page VMA [000000000003e000,000000000003efff] overlaps section .reserved_flash VMA [0000000000000000,0000000000077fff]
Build failed

How do I fix it?  I appreciate your help. TIA.

Hi, 

Looks like your rodate is overflowing into the mbr_params_page. i.e. rodata is ending at 77fff, while mbr_params_page is starting at 3e000. Please review your sections placement file and also the section placement macros in your project options.

pca10100_usb.zip

This is the bootloader file

Still I get the same error.

[Amanda Hsieh]

Hi, 

Modify FLASH_START to 0x69000 and that can fix the error. 

I also modify pca10100_usb_debug.7z  from pca10100_s113_ble_debug. In case you would need it.

It works. Thanks for support
