hey man, thank you so much. it is working.

#ifndef MEM_POOL_INTERNAL_H__
#define MEM_POOL_INTERNAL_H__

#define TX_BUF_SIZE 4u //600u /**< TX buffer size in bytes. */
#define RX_BUF_SIZE 32u //TX_BUF_SIZE /**< RX buffer size in bytes. */

#define RX_BUF_QUEUE_SIZE 8u//4u /**< RX buffer element size. */

#endif

I changed as you mentioned in the latest post. so It had been a buffer size issue. now I can able update the application and softdevice.

Hi,

[quote user="yuvasatheesh"]in that forum, they suggested reducing the stack size from 2048 to 255 in amr_startup_nrf51.s file.[/quote]

You should set this back to 2048.

Since you are using S110, you can instead adjust the IRAM1 value. Instead of start 0x20002C00, try start 0x20002000 and Size 0x1f80:

IRAM1 Start: 0x20002000
IRAM1 Size: 0x1f80

Also check that you have this buffer configuration (hci_mem_pool_internal.h):

#ifndef MEM_POOL_INTERNAL_H__
#define MEM_POOL_INTERNAL_H__

#define TX_BUF_SIZE       4u    /**< TX buffer size in bytes. */
#define RX_BUF_SIZE       32u   /**< RX buffer size in bytes. */

#define RX_BUF_QUEUE_SIZE 8u    /**< RX buffer element size. */

#endif // MEM_POOL_INTERNAL_H__
 
/** @} */

here I have attached the full example source which I am using currently.

1. bootloader source file.

2. actual softdevice file(s110_nrf51822_7.1.0_softdevice.hex).

3. test softdevice firmware(dfu_test_softdevice_b.hex) that need to update via ble.

4. this is the nrfutil command (nrfutil dfu genpkg --softdevice softdevice.hex --dev-type 0xffff --dev-revision 0xffff --sd-req 0x5a softdevice.zip).

I used a custom board with nrf51822 QFAA(16kb ram, 256 kb).

here's my attachment.

devzone.nordicsemi.com/.../8244.dfu.zip

please give me the solution.

I have already posted the nrfutil command. Please check in the image of the previous post.

The target device has flashed with s110_7.1.0_softdevice.hex and bootloader firmware.

Updating firmware got from test_ble_dual_bank folder in dfu example folder. I think the updating firmware file version is 0xFFFE.

Bootloader firmware atarted to advertise that named as ""DfuTarg".

[quote user="yuvasatheesh"]Here I have tried updating softdevice[/quote]

What SoftDevice version are you updating from and to ?

Can you post the nrfutil command you used to generate the zipfile package ?

Is application DFU working ?

please find the logs file. Here I have tried updating softdevice and got the error.

Is there any incompatible with the target device hardware specification?

RE: DFU with OTA

Satheeshkumar — Tue, 10 Dec 2019 18:07:24 GMT

That is a boot loader project. Please correct me if I made any mistake in the configuration settings

[quote user="yuvasatheesh"]I used the above settings and tried to build but I got an error like,[/quote]

Was this the application or the bootloader project?

[quote user="yuvasatheesh"]then the app started to upload the file to the target device. but failed. [/quote]

Did you get any error code in the app ? Anything in the log that might identify the issue?

RE: DFU with OTA

Satheeshkumar — Tue, 10 Dec 2019 06:32:44 GMT

Tried with NRF51822QFAA 16KB 256KB specification:

I used the above settings and tried to build but I got an error like,

Error: L6406E: No space in execution regions with.ANY selector matching arm_startup_nrf51.o(STACK).
Error: L6407E: Sections of aggregate size 0x800 bytes could not fit into.ANY selector(s).

and I searched in the forum and found one solution for this,

in that forum, they suggested reducing the stack size from 2048 to 255 in amr_startup_nrf51.s file.

Now the build was done successfully. I can flash into the target device. started advertising and connected with nRconnect chosen DFU option loaded zip file into the app. then the app started to upload the file to the target device. but failed.

please guide me if had done any mistake.

Thank u very much for your quick response. I tried with that nrfutil_0_5_2 still I am getting the same error. I need one clarification, this DFU process can support with 16 KB RAM, 256KB flash?

I can perform the same DFU with NRF51822QFAC 32KB 256KB specification. is there any possibility to do with NRF51822QFAA 16KB 256KB specification. Kindly help me.

[quote user="yuvasatheesh"]5.2.0[/quote]

Try using 0.5.2 instead:

devzone.nordicsemi.com/.../nrfutil_5F00_0_5F00_5_5F00_2.zip

nrfutil dfu genpkg --application APPLICATION.hex app.zip

I can generate the zip file using nrfutil.exe 5.2.0. I that image I have mentioned the exact command which was I used to generate the package.

I was tried to update the firmware of softdevice got from the example of bootloader testing (dfu_test_softdevice_w_bootloader_b.hex).

opened the nRF tools App and choose the DFU option.

select the device and select the zip file(chose as system component only) which is going to update. then click the upload button.

the target device has connected and App shows uploading and starting DFU then disconnected.

returns upload failed: OPERATION FAILED. (GATT ERROR)

Hi,

[quote userid="19762" url="~/f/nordic-q-a/55255/dfu-with-ota"]using nrfutil.exe[/quote]

What version of nrfutil did you use ? 0.5.x ?

See this and this link.
