This +has been tested in x86, ARMv7 and sandbox. + +To enable this, select CONFIG_CONSOLE_TRUETYPE. You can choose between several +fonts, with CONSOLE_TRUETYPE_NIMBUS being the default. + +TrueType support requires floating point at present. On ARMv7 platforms you +need to disable use of the private libgcc. You can do this by disabling +CONFIG_USE_PRIVATE_LIBGCC. See chromebook_jerry for an example. Note that this +increases U-Boot's size by about 70KB at present. + +On ARM you should also make sure your toolchain supports hardfp. This is +normally given in the name of your toolchain, e.g. arm-linux-gnueabihf (hf +means hardware floating point). You can also run gcc with -v to see if it has +this option. |
