nRF9160 FOTA using sdk2.1.0 and SPM fails to get flash area from ID

Hi Jonathan,

You're right, there is only this line that references the QSPI in the .config file in the build output files.

But it seems to me that the problem was really related to the QSPI, I tested this:

If the external flash device is not using the QSPI NOR driver, you must enable CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK

and now the regions.yml file has changed and has this override:

external_flash:
  base_address: 0x0
  default_driver_kconfig: CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK
  device: /soc/peripheral@40000000/spi@b000/mx25l6433f@0
  dynamic_partition: null
  name: external_flash
  placement_strategy: start_to_end
  size: 0x800000
flash_primary:
  base_address: 0x0
  default_driver_kconfig: CONFIG_SOC_FLASH_NRF
  device: flash_controller
  dynamic_partition: null
  name: flash_primary
  placement_strategy: complex
  size: 0x100000
otp:
  base_address: 0xff8108
  default_driver_kconfig: ''
  device: ''
  dynamic_partition: null
  name: otp
  placement_strategy: start_to_end
  size: 0x2f4
sram_primary:
  base_address: 0x20000000
  default_driver_kconfig: ''
  device: ''
  dynamic_partition: sram_primary
  name: sram_primary
  placement_strategy: complex
  size: 0x40000

and thus recognizes all areas created in the external flash!

However, I still can't do FOTA but it seems to me that now the problem is related to MCUBoot... 😞

So I'm going to close this case.

EDIT: my FOTA problem was resolved by applying this patch

Thanks for your help!

Regards,

Ricardo

Looks like you configs are correct and the device tree is configured seemingly correct.

I am not 100% sure how the regions.yml file is generated so not sure where it sources it info from, but can you check the .conf file in your build output files if there is anything named QSPI that is set to Y ?

There is likely only one line with QSPI and its

CONFIG_NORDIC_QSPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096

But that should be fine.

So unless there is no other differences in the regions.yml on the working version and this new update then i think we should not dig to deep on QSPI mention in the .yml file.

Hi Jonathan,

Yes, I still need your help!!!

The behavior is the same for different versions of the modem...

However, I noticed something else, in the file in build\regions.yml, the external flash is defined as:

default_driver_kconfig: CONFIG_NORDIC_QSPI_NOR

regions.yml:

external_flash:
  base_address: 0x0
  default_driver_kconfig: CONFIG_NORDIC_QSPI_NOR
  device: /soc/peripheral@40000000/spi@b000/mx25l6433f@0
  dynamic_partition: null
  name: external_flash
  placement_strategy: start_to_end
  size: 0x800000
flash_primary:
  base_address: 0x0
  default_driver_kconfig: CONFIG_SOC_FLASH_NRF
  device: flash_controller
  dynamic_partition: null
  name: flash_primary
  placement_strategy: complex
  size: 0x100000
otp:
  base_address: 0xff8108
  default_driver_kconfig: ''
  device: ''
  dynamic_partition: null
  name: otp
  placement_strategy: start_to_end
  size: 0x2f4
sram_primary:
  base_address: 0x20000000
  default_driver_kconfig: ''
  device: ''
  dynamic_partition: sram_primary
  name: sram_primary
  placement_strategy: complex
  size: 0x40000

why? The problem may come from here...

The nrf9160 does not support QSPI and the flash I think is configured correctly in the config file:

# External Flash
CONFIG_SPI=y
CONFIG_SPI_NOR=y
CONFIG_SPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096
CONFIG_SPI_NOR_SFDP_RUNTIME=y
CONFIG_FLASH_JESD216_API=y
CONFIG_SPI_NRFX_RAM_BUFFER_SIZE=32

Thank you for your help.

Regards,

Ricardo

Hi Jonathan,

I tested with version mfw 1.3.4 and the results are the same...

Hi,

mfw 1.3.5 does not have sdk 2.1.0 listed as compatible(tested) ref: https://infocenter.nordicsemi.com/topic/comp_matrix_nrf9160/COMP/nrf9160/nrf9160_modem_fw.html?cp=2_1_3_5
Could you try with mfw 1.3.4?

Jonathan
