请问AM3354驱动加载时卡住，偶尔系统崩溃是什么原因？SmartReflex 这个技术难度是有bug？还是说cpu间存在体制差异？

3332 cpu

问答对人有帮助，内容完整，我也想知道答案 0 本帖最后由一只耳朵怪于 2018-6-4 17:29 编辑 Hi，各位ti 的FAE，你们好我想请教一下关于SmartReflex的情况：最近公司产品所使用的AM3354（ SDK6.0 ），部分无法启动，大多是系统驱动基本加载完的时候，卡住，偶尔系统崩溃。 SDK6.0和3354已经用了2年多了，也不排除板子间（电阻电容）有所差异，但原理图是绝对没有改变过的。调试：1. 产品Boot里面设置CPU 频率 600，电压参考800频率的电压，内核带SmartReflex，CPUFreq governor 使用userspace； 2. 当boot把cpu改为800时，有问题的产品大多能启动，偶尔还是跑崩 3. 当把内核SmartReflex 取消，产品启动就没有任何问题了。 4. 部分产品还用 SDK7.0，SDK7.0里面却已经没有SmartReflex 这个东西，SDK7.0启动也没有任何问题。问题：SmartReflex 这个技术难度是有bug？还是说cpu间存在体制差异？ SDK之间的差异有没有可能说明一下？例如SDK6.0 对于u***虚拟多个串口就存在很多bug，而SDK7.0对于wl1271这个模块支持的不太好。 0

答案对人有帮助，有参考价值 0 目前AM335x上面使用的SmartReflex是Class 2B的，软件上面从SDK 5.05，很老的一个版本就开始支持了。 http://processors.wiki.ti.com/index.php/Sitara_SDK_5.05.00_Release_Notes?keyMatch=smart%20reflex%20on%20AM335&tisearch=Search-EN#What.27s_New 迄今为止，我所遇到的这种情况基本上都是由于电压供电的电源质量问题引起的，所以我之前写过一个汇总，建议你可以参考这个排查一下，电源质量方面的差异：AM335x电源问题汇总至于版本间的差异，可以参考release notes： http://processors.wiki.ti.com/index.php/Sitara_Linux_Software_Developer%E2%80%99s_Guide
