Sep 1, 2025Month: 2025-09 - SiFli-SDK focused on expanding hardware compatibility, stabilizing builds, and improving developer experience. Key features delivered included adding support for sf32lb56-lcd_n16r12n1 board to the GPIO example, with updated platform coverage, pin mappings, and build steps. Major bugs fixed included resolving a compilation error for audprc on sf32lb58-lcd_a128r32n1_dsi by adding a missing macro and enabling AW8155, as well as correcting a documentation typo in the finsh/finish example to reflect the function name 'myhello'. These changes contribute to broader platform support, more reliable builds, and clearer documentation.
