I am trying to use our own flasher for a Micron 32MB (MT25QL256ABA) on a spi bus. With J-Flash V7.88
But I get some strange info and behavior when selecting the flash.

Create the project




But by default the "Sector selection" only selects the first 65535, then select the rest





Then also the "Sector selection summary" is also wrong




I can now use the flasher to program. but only op to 0x70FFFFFF if I try to proram at 0x71008000 Then I get this error



The definition in my config file under "C:\Users\***\AppData\Roaming\SEGGER\JLinkDevices\ST\STM32H730VB.xml"
