I Have already designed some application on K60F150, K70F150, with MQX 4.2 and PEG.
For a new application, we need a µC with 2MB Flash and 256KB of RAM to avoid use a sqm4 K70 bord to reduce the cost.
Is the K66F180 is supported by MQX 4.2? Because into it, there are repository for K60 ,64, 65 and 70 but not for K66.
K65 seems to be the 1MB flash supported, not the 2MB.
Do you think I can use the K65f180 and just modify the linker file to extend flash from 1MB to 2MB?
K66 Board is supported in MQX v5 , it is under low-cost commercial license terms. Please check below link for more details.
If you want to port from K65f180, it is also possible, please read the porting guide in the MQX 4.2 installation folder. Just modify the linker file is not enough.
