Can I only update Logic program without download image and font resources？

[Wrend.1]

Now my program use lots of image and ​font resources, it make the size of applications becom very large. So I need use large time to download the program with keil. When I Modified logical code and the resources not changed, how can I only download logic program in a short time?

By the way, if I want to do OTA, I must update the program in a short time. So this is very important to me

You can split the resulting binary into seperate binaries based on the memory ranges and then just program the internal range if there are no changes to the external range (e.g. QSPI 0x90000000).
