Hi , I am using ZEPHYR rtos , and using the internal bootloader and its working fine and there are two images but now my code size has increased and i can not store 2 images in internal flash so have to do implementation of saving the image to external flash and after validation move to internal flash ,what changes i require to make in zephyr bootloader to add external flash code(SPI) and using only 1 image in bootloader
Hi Anil,
Please provide what exact error do you receive ? Do you have any debug log ?
Note that it's not possible (as far as I know) to boot from the external flash. What you can do is to receive the image in the secondary slot and then swap the image to the primary slot (the internal flash)
Please let us know what's your modification, which flash library, how you configure the device tree and the partition manager (partitions.yml file).
Do you have the Dev Kit ? You can test my example on the devkit and then change the QSPI interface to SPI interface. It's easier if we have the same hardware and can test here.
Hi Hung ,
what can cause this issue also attaching my project files
00> *** Booting Zephyr Otonga_nrf52833.dtsS build v2.4.99-ncs1 ***usb_cdc_acm_log_recovery.conf
00> I: Starting bootloader 00> W: Failed reading sectors; BOOT_MAX_IMG_SECTORS=512 - too small?
00>E: Image in the primary slot is not valid!
00> E: Unable to find bootable image
this is the error i am getting ,this is exactly what i wanted to do save the file in external flash and then move it to internal flash,
this is my partotion file below
Hi Hung,
Already have done that also added that in dts file but result is still the same having the same problem

Hi Anil,
- Please let us know if you have tested the example I provided ?
- Do you have Devkit (nRF52840/nRF52833) to test ?
- I'm not 100% sure but why you use "zephyr,pm-ext-flash = &mx25r64;" instead of "nordic,pm-ext-flash = &mx25r64; " ?
- Please send us your test project including the build folder.
