      The MMCSD driver uses the snprintf calls here:

      https://github.com/TexasInstruments/mcupsdk-core-k3/blob/k3_main/source/drivers/mmcsd/mmcsd_priv.c#L92-L92

      Following is the image size with the default code:

      ❯ /usr/bin/ls -l sbl_emmc_linux_stage1.release.hs_fs.tiimage
-rw-r--r-- 1 p-shivhare p-shivhare 270967 Mar 17 13:16 sbl_emmc_linux_stage1.release.hs_fs.tiimage

      If instead of the snprintf from libc, we use the snprintf_ from the DPL printf.c, the image size reduces by ~4KB:

      ❯ /usr/bin/ls -l sbl_emmc_linux_stage1.release.hs_fs.tiimage
-rw-r--r-- 1 p-shivhare p-shivhare 266231 Mar 17 13:16 sbl_emmc_linux_stage1.release.hs_fs.tiimage
