    • Reply: V853烧录问题后自动重新烧录

      @null037
      兄弟,可以帮忙看下我这个问题吗?是不是也是芯片问题呀。这颗EMMC芯片也不在这个手册里面。[allwinner-v853-emmc-flash-support-list_v1.0.pdf]

      我这个开机打印没有你帖子里面的打印的内容多。

      @whycan
      目前用同样的固件可以烧到开发板上,在自己做的板子上面就是烧不进去。没有下一步了。目前的打印就是这样。

      @whycan 在 V853 无法烧录问题@whycan晕哥 中说:

      @wl17761275256
      固件是OK的吗?

      固件在开发板上下载过

      1、板子上面只有EMMC,没有TF卡和Flash其他的。
      2、PC的启动顺序,我确认下。但是我用开发板插上USB是可以烧录看到进度条的。

      硬件背景
      1、原理图参考官方双目开发板,电源管理使用 AXP2101。
      2、EMMC使用妙存-AT70B08G3S03F。上电测试EMMC_CLK是50MHz波形。

      烧录操作
      1、开机上电USB供电5V。
      2、使用PhoenixSuit.exe软件烧录固件。

      3、附图烧录

      4、附开机打印日志
      开机打印.txt

      打印到最后就没有了。一直停在这个位置

    • V853的BOOT-MODE选择

      7672ccbd-d58c-426e-aae2-bf2ecf58f9e3-图片.png

      1、确定如何选择GPIO Pin Select 和 eFuse Select 这2种模式如何选择。
      2、硬件选择对应的管脚是哪个呢。
