Hi,

Are you using S140 for nRF52833?

[quote user=""]i`m doing a single bank update. So far works well. But now the app grown am little and now i, running in failure NRF_DFU_RES_CODE_INVALID_PARAMETER.[/quote]

Can you try to debug the bootloader project and see why it returns NRF_DFU_RES_CODE_INVALID_PARAMETER? According to this it is because: "The specified size for a data object is not page aligned, and it is not the last object."

Try to set the bootloader start at 0x78000 if you are using nRF52833.

Regards,
Amanda H.

Update:

seem some settings for single bank wrong or missing.

Flash area for app is 0x27000 to 0x6D000 (bootloader start at 0x6D000)
During update process i can write app till address 0x4A000,
0x27000 + 0x23000 = 0x4A000
0x27000 + 0x23000 + 0x23000 = 0x6D000

So i guess some settings for single bank missing or wrong

For bootloader followein settings are done:

#ifndef NRF_DFU_FORCE_DUAL_BANK_APP_UPDATES
#define NRF_DFU_FORCE_DUAL_BANK_APP_UPDATES 0
#endif

// <o> NRF_DFU_HW_VERSION - Device hardware version.
// This is used to determine if given update is targeting the device.
// It is checked against the hw_version value in the init packet

#ifndef NRF_DFU_HW_VERSION
#define NRF_DFU_HW_VERSION 52
#endif

// <q> NRF_DFU_REQUIRE_SIGNED_APP_UPDATE - Require a valid signature to update the application or SoftDevice.

#ifndef NRF_DFU_REQUIRE_SIGNED_APP_UPDATE
#define NRF_DFU_REQUIRE_SIGNED_APP_UPDATE 1
#endif

// <q> NRF_DFU_SINGLE_BANK_APP_UPDATES - Place the application and the SoftDevice directly where they are supposed to be.

// Note that this creates security concerns when signing and version checks
// are enabled. An attacker will be able to delete (but not replace)
// the current app or SoftDevice without knowing the signature key.

#ifndef NRF_DFU_SINGLE_BANK_APP_UPDATES
#define NRF_DFU_SINGLE_BANK_APP_UPDATES 1
#endif
