nRF connect SDK ,Matter OTA

Question

Hi,

We are debugging the OTA function of Matter and using nrf52840 IC, but our board is relatively small, so we cannot use the Flash IC of the example; We are using IS25LP080D;

We have modified the relevant configuration of QSPI and the program can run correctly, but we encountered a problem during OTA,

The UART printing information is as follows:

May I ask what error this may be? Thank you for your help
