Thank you for your patience.
LM25185 is a PDS Flyback converter that has an integrated 42V/1.5A. The power that you need to deliver is 170V*0.6A+12V*0.5A=108W. To be able to deliver that power with a VIN=9V-16V, you need a high current MOSFET at the primary…
楼主，你们用这款Nand Flash跑起来了吗？我们计划升级系统，Nand Flash也是选的这款。
刚好我们的u-boot也是这个版本，我刚刚对了下代码，除了你修改的那些配置项，有一个地方要试一下：
