Thank you Einar, for your support

Searching for "SoftDevice Controller build revision" in the NCS code you see that this is from nrf\subsys\bluetooth\controller\hci_driver.c. And the same, searching for " Sectors of " you se that the first lines are from zephyr\subsys\fs\nvs\nvs.c

HI, Yes i understand your point

I just want to not print these lines and rest of the lines i need to print

I: 2 Sectors of 4096 bytes

Where are these lines located ?

Hi,

With the suggested modifications you disable all printouts. But the application and mcuboot are separate binaries, so if you do not want to print anything in the mcuboot either you need to do the same modification there.

2. Is printf() and printk() same?

3. How to control to print only the blue lines

In most cases you can disable printouts using CONFIG_SERIAL=n, but you can also use CONFIG_UART_CONSOLE=n and CONFIG_PRINTK=n if needed.

Hi,

I am not sure you will save any space on that unless you remove loggign alltogether. That said, you can disable printk by putting CONFIG_PRINTK=n in your prj.conf.

Hi Einar,

Happy Easter.

OK, Is it possible to disable printk

and enabling printf "uart print"

RE: NCS OTA DFU failed in nrf52832

Einar Thorsrud — Tue, 06 Apr 2021 13:11:45 GMT

Hi,

The only thing you need to consider is that slot o and slot 1 must be of equal size, and your application must fit in one of the slots. If it does not you must try to shrink the application. If not possible, you must use a device with larger internal flash or use external flash for slot 1.

Hi Einar,

How do i manage the memory in NCS DFU example for nrf52832.

Does NCS DFU support have any limitation ?

RE: NCS OTA DFU failed in nrf52832

Einar Thorsrud — Thu, 25 Mar 2021 10:46:10 GMT

I should note that the sizes from my last answer was with unmodified sample, so not including mcu_mgr which you need.

The point remains that your slots must be equally sized and the application most fit in the slot. If it does not this will not work, no matter how much you try. If you are unable to make the application fit then you need to either not include DFU support (typically a bad idea for real products) or use a nRF device with more internal flash or use an external flash memory for slot 1.

Hi,

The unmodified peripheral_lbs sample from NCS 1.5 is 162872 byte, so that would fit. But if you build it with debug optimization the size increases to 184388 which is still within the limit. What is the size you get when you build it?

RE: NCS OTA DFU failed in nrf52832

Sunil vignesh — Tue, 23 Mar 2021 10:02:54 GMT

Hi Einar, Actually seeing I doesn't change any application file rather . i have use only the example of LBS code with DFU.

Is it means that example code has more than 200KB?

RE: NCS OTA DFU failed in nrf52832

Einar Thorsrud — Tue, 23 Mar 2021 09:56:06 GMT

Hi,

The memory layout you have in this post is the same as in the SDK and fits the nRF52832 with 512 kB flash. So this is correct. this means that your application size must be less than the size of the slots, which is 0x32000 bytes = 200 kB. So to make this work you need to shrink your application slightly or use a nRF device with more flash or use an external flash memory for slot 1.

As per the note I have changed the .dts file

partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		boot_partition: partition@0 {
			label = "mcuboot";
			reg = <0x00000000 0xc000>;
		};
		slot0_partition: partition@c000 {
			label = "image-0";
			reg = <0x0000C000 0x32000>;
		};
		slot1_partition: partition@3e000 {
			label = "image-1";
			reg = <0x0003E000 0x32000>;
		};
		scratch_partition: partition@70000 {
			label = "image-scratch";
			reg = <0x00070000 0xa000>;
		};
		storage_partition: partition@7a000 {
			label = "storage";
			reg = <0x0007a000 0x00006000>;
		};
	};

check the size whether i made it correct ?

Even though I changed it like above I got same no free space issue

RE: NCS OTA DFU failed in nrf52832

Einar Thorsrud — Fri, 19 Mar 2021 09:09:27 GMT

Hi,

You need to ensure that the app is small enough to fit in one slot, and the slots need to have the same size in order for this to work. Also, you cannot just increase the size of the slots without moving other things around, and ensuring that there is not enough space. In short, the default dts has the sensible configuration here. Your changes will not work. Let me explain.

Original partition layout of slot0 and slot1:

		slot0_partition: partition@c000 {
			label = "image-0";
			reg = <0x0000C000 0x32000>;
		};
		slot1_partition: partition@3e000 {
			label = "image-1";
			reg = <0x0003E000 0x32000>;
		};

Here you see that slot 1 starts at the end of slot 0 (0xC000 + 0x32000 = 3E000)

Your layout:

slot0_partition: partition@c000 {
            label = "image-0";
            reg = <0x0000C000 0x34000>;
        };
        slot1_partition: partition@3e000 {
            label = "image-1";
            reg = <0x0003E000 0x34000>;
        };

Fullscreen

Here you increase the size of the slots, but you do not move slot 1, so there is an overlap. So if you should do this, it must be something like:

		slot0_partition: partition@c000 {
			label = "image-0";
			reg = <0x0000C000 0x32000>;
		};
		slot1_partition: partition@3e000 {
			label = "image-1";
			reg = <0x0003E000 0x32000>;
		};

But then the end of slot1 is at 0x74000, so this overlaps with the scratch_partition, and so on. So you need to move everything down.
