DM368串口烧写没法往下行

2019-07-26 20:14发布

      各位大家下午好,情况是这样纸滴。开发的DM368 IPNC,买的APPRO的方案IPNC_DM368_IMX036,板子焊好后上电用CCS3.3连不上,SEED-XDS510PLUS仿真器的灯闪都不闪,但是用仿真器连样板能连上。于是尝试串口烧写工具,把UBL和UBOOT通过串口烧进去串口打印如下,就只停在“waiting for sending sequence"这一句不动了,这是不是和NAND FLASH连不上啊:


  原理图只是在样板的基础上删除了一些不需要的外围电路(MIC,音频输出和模拟视频YPbPr输出),外围电路删除后没用的GPIO口也按手册要求做相应处理了,FLASH、DDR2选型和样板一样,为K9F1G08UOB、K4T1G164QA,仔细检查FLASH、DDR和电源电路没有问题,万用表量供电正常,和样板一模一样,PCB上贴件也正确,PCB板也控了阻抗,有没有遇到过这种情况的兄弟姐妹麻烦出来指点迷津,十分感谢。还有就是看网上有人说DM368串口烧APPRO给的UBL和UBOOT有问题,但是烧TI的UBL和UBOOT可以烧进去,这TI的DM368UBL和UBOOT去哪里下呢,我找了一圈都没找着,希望知道的告诉一声。再次感谢。

贴图看不到了,再次把打印信息给复制上:
