KT200 and Foxflash programmer will read and write PSA Peugeot Citroen DCM7.1A/B in boot without problem. But it is EXTREMELY difficult.
You need a lot of patience to find the boot pin under the processor.
NEW BOOT MODE FOR DELPHI ECU DCM7.1A / DCM7.1B
BOOT MODE for micro AURIX TC297 mounted on DCM7.1A and DCM7.1B control units of the PSA group.

DIRECT BOOT & CNF1 CONNECTION
One of the BOOT pins is placed under the microprocessor
WARNING: we recommend using and tilting a metal support rod with a needle to reach the BOOT pin located under the microprocessor.
with the right tweezers it’s done on its own. just need good eyes / magnifying glass
this cnf1 for kt200
also power/gnd/canH/CanL on ecu pins
Foxflash will read and write DCM7.1a/b in boot mode as well, same instruction as kt200.
Example:
1. Citroen jumper dcm7.1b – read/write, the checksum is made by the tool
2. PSA 2020 year DCM7.1A boot. Read/Write ok with foxflash, checksum by tool.
3.
Citroen Jumper 2.2 2020 Dcm7.1b Read and Write ok
4.
Citroen jumper dcm7.1b – read/write, the checksum is made by the foxflash tool).
5. Dcm7.1A kess v3 autotuner , flex v2 all failed ,
So amazing but foxflash worked
