mcuboot_opensource + lwip_httpsrv_ota_enet on the evkmimxrt1064

[sugarsplash]

I have been attempting to follow previous suggestions and posts such as https://community.nxp.com/t5/i-MX-RT/Update-image-of-signed-application-Fails-for-lwip-httpsrv-ota/t...

But I am having trouble getting through the lwip_httpsrv_ota_enet example. Would like to demonstrate the following on my dev board before moving to a custom pcba:

1. A flash resident second bootloader
2. ability to flash applications to flash over Ethernet

Firstly, building and flashing the mcuboot_opensource example seems to work find and as expected. 

J-Link>loadfile MCUXpressoIDE_11.6.1_8255\workspace\evkmimxrt1064_mcuboot_opensource\Release\evkmimxrt1064_mcuboot_opensource.bin 0x70000000
'loadfile': Performing implicit reset & halt of MCU.
ResetTarget() start
ResetTarget() end
AfterResetTarget() start
AfterResetTarget() end

O.K.

When attempting to subsequently flash the lwip_httpsrv_ota_enet application, I am interested in using the "direct method"

a) programing signed application image to the primary application partition using an external tool (direct method)
b) jump-starting the application by debugger, performing OTA update with the signed image, resetting the board and letting the bootloader to perform update (indirect method)

When attempting the direct method, I first sign the image:

(venve) nxp_sdk\middleware\mcuboot_opensource\scripts>python imgtool.py sign 
    --key nxp_sdk\boards\evkmimxrt1064\mcuboot_opensource\keys\sign-rsa2048-priv.pem 
    --align 4 --header-size 0x400 --pad-header --slot-size 0x200000 
    --max-sectors 800 --version "1.0" MCUXpressoIDE_11.6.1_8255\workspace\evkmimxrt1064_mcuboot_opensource\Release\evkmimxrt1064_mcuboot_opensource.bin http_ota_signed.bin

I then flash this signed image: 

J-Link>loadfile http_ota_signed.bin 0x70040000
'loadfile': Performing implicit reset & halt of MCU.
ResetTarget() start
ResetTarget() end
AfterResetTarget() start
AfterResetTarget() end

It looks like sbl accepts this as a bootable image but the image crashes when loaded. 

hello sbl.

I am hoping someone may be able to help point me in the right direction. Could this be an issue with my built lwip_httpsrv_ota application or perhaps how I am signing and flashing?  Attaching my signed and unsigned bin files if that helps.

Omg, I signed the wrong file. I have been accidentally flashing the mcuboot_opensource binary to slot 1. I am ashame.
