Flexspi nor polling transfer example not working

[_bjs]

Hello,

FlexSPI NOR polling example giving me following result:

FLEXSPI example started!
Vendor ID: 0x0
Erasing whole chip over FlexSPI...
Erase finished !
Erasing Serial NOR over FlexSPI...
Erase data - read out data value incorrect 

 
I am trying to go from HyperFlash to QSPI on the IMXRT1050-EVKB.
I have updated the OpenSDA ( i think does not matter this example is not writing to flash)
I have changed the boot mode, and ofcourse placed/removed the resistors as from:
AN12108 

Please help

Found it, resistor place/remove double check and now:

double check the development board and the manual.
correctly change the correct resistores given in the document:
