Hi @kwf ,
Thanks for your confirmation.
I checked it on my side, RT1170 ROM is changed, it don't use the sdphost to connect the chip in the serial download mode, it use the blhost to connect and load the ivt_flashloader to the RT1170 directly.
You can refer to the MCUBootUtility tool log:
Executing: C:\KerryPC\tool\NXP-MCUBootUtility-3.3.1\tools\blhost2_3\win\blhost -t 50000 -u 0x1FC9,0x013D -j -- get-property 1 0
toolStatus: 0
commandOutput: {
"command" : "get-property",
"response" : [ 1258487809 ],
"status" : {
"description" : "0 (0x0) Success.",
"value" : 0
}
}

toolStatus: 0
commandOutput: {
"command" : "get-property",
"response" : [ 0 ],
"status" : {
"description" : "0 (0x0) Success.",
"value" : 0
}
}

commandOutput: {

}
}

}
So, just use the blhost directly after you enter the serial download mode to the RT1170, sdphost don't need to use to load ivt_flashloader.bin now. It is the different to the RT10XX in the ROM.
From RT11XX, ROM is changed, discard the sdphost, just use the blhost is enough, thanks.
Wish it helps you!
If you still have questions about it, please kindly let me know.
