After porting from an older version of TouchGFX (4.9.3) to 4.13 the fonts section become huge

egoltzman · ‎2020-01-19

Hi,

I ported successfully 4.9.3 application to 4.13, the process worked well and I can see the application running under the simulation.

I tried to build the application under CubeIDE, the compilation and link passed successfully but from some reason the new version created a very large font section (More then 1M while it was around 90K)) that did not fit in the internal flash as before.

This is a short snippets from the map file of the new build:

FontFlashSection
                0x0000000091ee26b8   0x17d88c
 *(FontFlashSection FontFlashSection.*)
 FontFlashSection
                0x0000000091ee26b8     0x12f7 generated/fonts/src/Font_Poppins_Bold_16_4bpp_0.o
                0x0000000091ee26b8                unicodes_Poppins_Bold_16_4bpp_0
 *fill*         0x0000000091ee39af        0x1 
 FontFlashSection
                0x0000000091ee39b0      0x664 generated/fonts/src/Font_Poppins_Bold_16_4bpp_1.o
                0x0000000091ee39b0                unicodes_Poppins_Bold_16_4bpp_1
 FontFlashSection
                0x0000000091ee4014    0x121a9 generated/fonts/src/Font_Poppins_Bold_16_4bpp_28.o
                0x0000000091ee4014                unicodes_Poppins_Bold_16_4bpp_28

in compare to the old build:

FontFlashSection
                0x0809381c    0x16a5a
 FontFlashSection
                0x0809381c     0x130f generated/fonts/src/Font_Poppins_Bold_16_4bpp.o
                0x0809381c                unicodes_Poppins_Bold_16_4bpp

Can you please explain what cause this change, and if and how I can reduce the size?

Thanks

Hi Eyal,

Can you check the content of your generated font cpp files? Does it contain a lot more glyphs than you asked for? (Your defined ranges in the designer).

I've heard about someone else having this issue before.

Hi Martin,

I checked that and indeed the generated cpp are huge, I have defined ranges in the application but in the 4.9.3 version the generated cpp was much smaller so I assume (I'm not sure how to check) that in the new version I have more then I requested.

How can I fix this?

Thanks,

Eyal

Hi Martin,

Any input on that?

Thanks

Hi Eyal,

Can you show me your unicode ranges? Can you do some experiments for me? Narrow your ranges and verify in generated code that you're getting only what you asked for - Until you don't. It's not something we've experienced yet, but i saw another user who did who solved it using a new version of his font.

But, since it works for older versions of TouchGFX there really shouldn't be a difference.
