By default, the checksum is not verified in order tospeed up the booting process. To turn on checksum verification,set the global variable <b>inflateCksum</b> to TRUE in the BSP.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK or ERROR.</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./inflateLib.html#top">inflateLib</a></b></body></html>⌨️ 快捷键说明
