Hi,

Thank you for the update. Yes, it's best to set CONFIG_GPIO_AS_PINRESET=n as the default configuration. This ensures that all images, including child images such as MCUBoot, won't attempt to enable the pinreset functionality on P0.18.

Hi,

sorry for late response, I was out of the office and I tried to investigate it a little bit more and I found the problem. Due to the external flash SCK pin is connected to pin P0.18 (which is also reset pin) I had in my prj.conf CONFIG_GPIO_AS_PINRESET=n. However I had to add this configuration to the board file structure to file {board_name}_defconfig. This solved my problem and the error doesn't occure at the boot anymore.

Thank you for your time.

Could you please try to compare the register configurations when you run the SPI flash sample and the Matter sample to see if anything is different? Relevant registers to compare are:

- PIN_CNF[n] for all pins assigned to QSPI

- QSPI registers: Registers

It is also recommended to configure the GPIOs in high drive mode. You can do this by using the 'nordic,drive-mode' property in your pinctrl overlay:

	qspi_default: qspi_default {
		group1 {
			psels = <NRF_PSEL(QSPI_SCK, 0, 18)>,
				<NRF_PSEL(QSPI_IO0, 0, 20)>,
				<NRF_PSEL(QSPI_IO1, 0, 24)>,
				<NRF_PSEL(QSPI_IO2, 0, 22)>,
				<NRF_PSEL(QSPI_IO3, 0, 15)>,
				<NRF_PSEL(QSPI_CSN, 0, 13)>;
				nordic,drive-mode = <NRF_DRIVE_H0H1>;
		};
	};

Thank you for explaning me why these settings were disabled for my board.

Yes, I still see the same log form the application. How can I enable logging from the bootloader, please?

PS: my external flash is connected to nrf52840 as follows:

	qspi_default: qspi_default {
		group1 {
			psels = <NRF_PSEL(QSPI_SCK, 0, 18)>,
				<NRF_PSEL(QSPI_IO0, 0, 20)>,
				<NRF_PSEL(QSPI_IO1, 0, 24)>,
				<NRF_PSEL(QSPI_IO2, 0, 22)>,
				<NRF_PSEL(QSPI_IO3, 0, 15)>,
				<NRF_PSEL(QSPI_CSN, 0, 13)>;
		};
	};

The reason the CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE=16 and CONFIG_CHIP_QSPI_NOR=y settings were not enabled by default is that the default settings are not applied when building for another board:

https://github.com/nrfconnect/sdk-connectedhomeip/blob/master/config/nrfconnect/chip-module/Kconfig.defaults#L179 and https://github.com/nrfconnect/sdk-connectedhomeip/blob/master/config/nrfconnect/chip-module/Kconfig.features#L49.

Are you still seeing the same log from the application, and do you have logging from the bootloader enabled?

Hello,

Thanks for confirming. I have reached out to our Matter team to see if they have any thoughts on what the problem could be. Will let you know when as soon as I've heard back from them.

Hello,

I tried to reduce clock speed 4 times to sck-frequency = <2000000> but the error is still there.

Hello Filip,

[quote user="filipmrazek"]The qspi section of the .dts file is same except used pins.[/quote]

Even though your HW works with the SPI flash sample, could you please try to reduce the QSPI clock speed to see if it makes any difference. The QSPI is not guaranteed to work at higher frequencies when not using the recommended Pin assignments.

Best regards,

Vidar

Hello Vidar,

I compared .config and zephyr.dts files of my custom board with dk board. The qspi section of the .dts file is same except used pins. However, in .config file I found two keys related to qspi memory, which were missing in my .config (CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE=16 and CONFIG_CHIP_QSPI_NOR=y).

I added them to my prj.conf but the same error is still there.

Do you have any other idea what could be wrong?

Best regards,

Filip

Hello,

Could you please compare (diff) the .config and zephyr.dts file in <build dir>/zephyr when built for the 'nrf52840dk_nrf52840' and when built for your custom board to see if anything stands out? The fact that the spi flash example runs OK is a good sign.

Best regards,

Vidar
