Hi Maulik,

Thanks for your support.

1. I think I understand why you don’t get the error on the Musca-B1. In fact, we are not using the same flash driver: 1.1. My build uses the `emulated_flash_dvr`, which checks that the byte is erased in flash before attempting a write (this is where I get the error). 1.2. The Musca-B1 platform uses the `qspi_ip6514e_drv`, which does not perform such a check before writing to the flash. From what I understand, the MT25QL Series Flash NOR does not return an error even if you try to write a 1 in a bit that was 0. As such, you do not encounter the error. 2. It is strange that you don’t get the warning when MCUBOOT_CONFIRM_IMAGE=OFF.

Best regards, Cédric
