We don’t have kits for LQFP144 package.
Are you planning to use High-Speed Quad SPI for the serial flash memory? If yes, the 144 LQFP package does not have HS-QSPI. Please make use of "Package Dependent Features” table at page n:5 of the datasheet. Instead you can choose another package for this feature.
Furthermore, if you are fine with traditional single port SPI to connect the flash memory, please make use of MFS5 (pin #93 ~ #97 for LQFP144 package) instead of the HS-QSPI.
