t113-s3因为硬件原因导致内核无法启动

[cjia3254]

现尝试自编译的tina，在boot0和uboot阶段都有输出，内核没有。
采用awboot的方式引导主线内核的方式，在boot阶段也有输出，内核没有。
尝试使用芒果派的mq-r-t113-rtl8189fs-5113-dns-uart0.img，在boot0和uboot阶段也都有输出。
所以我判断是因为硬件问题导致内核无法启动。
VCC-PLL=1.8v
RESET=3.3v
LDOA-OUT=1.8v
LDOB-OUT boot0未启动时1.35v，启动时1.5v
vcc-pe=1.8v
VDD_SYS0=0.9v
VCC-DRAM0=1.5v
VDD18-DRAM=1.8v
VDD-SYS1=0.9v
LVDS18=1.8v
VCC-PD=3.3v
VCC-TVOUT=3.3v
VDD-SYS2=0.9v
VCC-IO=3.3v
AVCC=1.8v
HPVCC=1.8v
VCC-TVIN=1.8v
VDD-CORE1=0.9v
VCC-PG=3.3v
望大佬解惑

正常的，内核没有输出检查一下设备树配置

@awwwwa 说来奇怪，我最近画的一块d1s也是这样的情况，boot0和uboot都能启动，就到内核没输出了

@cjia3254 earlyprint跟串口配置对了吗

[cjia3254]

@jingyan 这个我测试过，固件在另外一个d1s板子上能正常工作，在我新画的这个上面到内核就没输出了。

[Jingyan]

@cjia3254 确认下是卡死在内核了，还是只是没打印到终端上

[Asoul_Ava]

@cjia3254 我最近也有这样！多按几次复位有几率能进入

[fanhuacloud]

看着像是读取有问题

[cjia3254]

又重新画了块t113的板子，加了几个滤波电容，就能正常启动内核了。

[Asoul_Ava]

@cjia3254 你好，请问是在哪个部分要加滤波电容？

[cjia3254]

@asoul_ava 是个电源供电都加电容了。
