• nxp uuu工具

    目前正在学习研究uuu工具对nxp系列平台进行刷机操作,现遇到问题: uuu可以将image file直接烧写进UDA,那么这个image file如何制作?bitbake似乎无法生成img? 关于LOADADDR的一些疑问,这个LOADADDR的地址如何确定?以IMX6UL为例: 8000_0000为内存起始地址,理论上我们可以将LOADADDR设定为8000_0000~FFFF_FFFF中的任何位置。 我还接触...

  • IMX6ULL 热复位无法从EMMC FLASH启动

    大家好,       我的一款设计中,IMX6ULL从EMMC FLASH(SD2接口、4GB)中引导启动。电路板上电后,由USB OTG下载程序,再断电重新上电,串口输出打印信息。后续每次断电重启,CPU都能正常引导,串口输出正常,其他所有功能都正常。但在带电工作中,按下手动复位键(已量CPU的POR#引脚同时变低,以确保复位电路是正确的),CPU不复位(或者可能CP...
