最近做了一个全志H3双DDR方案,有合作的伙伴,可以来聊

#3 全志 SOC » 【全志H3】EMMC的MMCBLK分配问题 » 2024-08-01 10:43:13

情况:使用orangepi的源码,生成的img镜像,开启内核日志和关闭内核日志两个情况下,emmc分配到的mmcblk编号会发生变化
硬件设计:SD卡连接SDC0,XR819连接SDC1,EMMC连接SDC2,是数据手册上这么写的

留意到的问题
第一个是uboot启动阶段
MMC:   Device 'mmc@1c11000': seq 1 is in use by 'mmc@1c10000'
mmc@1c0f000: 0, mmc@1c10000: 2, mmc@1c11000: 1
其中mmc@1c11000是SDC2上的EMMC, mmc@1c10000是SDC1上的XR819 WIFI

第二个是内核启动阶段的,我调整WIFI的启动时间post-power-on-delay-ms = <200>;,发现EMMC的启动是跟着它走的,按理来说不应该一起才对

供应商那边指导说是没有关联,但我看着这个信息和日志对不上,不知道哪个是对的

请问哪位知道他们是不是有关联么

几年前在挖坑网上发了第一个帖子,是全志的H3核心板,最近在网友的大力支持之下,又做了一版双DDR方案,分享一下

除了V3S,你还应该看看其他的元器件,是不是扛得住

#11 Re: 全志 SOC » 有哪位兄弟V3S做过-40度运行测试啊? » 2021-01-11 17:34:12

这么低温度?你去查下数据手册吧。因为V3S本来是做行车记录仪的,我猜它的温度范围应该是-40℃~+125℃
商业级器件的工作温度范围是0℃~+70℃,工业级的是-40℃~+85℃,军品级的是-55℃~+150℃。
汽车工业级的是-40℃~+125℃。

其实吧,要不是这个产品能有千八百万的纯利,没谁会去想着破解你的,随便做点加密就行了,但是呢,要是利润那么高,又不如直接重新开发来得好

可以了,现在能正常跑在400多M了

焊接完新的板子

可以确定到300多M的时候,板子还能跑起来,到了400多M就废了,有意思的是,800多M的时候,竟然测试通过了
很明显是不正常的
阅读LOG,发现好像测了两片DDR3,但是我实际上只有一片,读了一下手册,也没有哪个地方说可以设置为一片DDR
现在ddr_init的参数被我改乱了,回头再重新下个软件,看看能不能通过配置,让芯片跑在400多M

4层板阻抗很难做到连续,连个参考面都找不出,稳定性不好保证,不知道啥时候就出些奇奇怪怪的问题。 还是上6层板,换高规格工艺吧,打样也就2000多。

不弄6层,自己玩,没必要投入这么多

400是源码里面设置的,准确的说,源码里面设置的是408M
重新做一版,争取上800M

试了下降低DDR频率,果然可以很稳定的启动

这是正常启动的样子

恭喜哇, 这是正常操作, 中科世为的A33板子一样DDR要降频才能启动,达不到主线uboot的默认配置速度.

恩,我决定再优化一波,毕竟一个1000多M的DDR,跑出个两三百M,还是有点丢人了
目前打算是一个邮票孔+一个金手指的底板,这样就可以到处插了

#21 Re: 全志 SOC » 自制全志H3核心板 » 2020-12-21 23:17:29

20201221
下一步,有两个计划:
1.在这个基础上,优化PCB,把DDR支持的频率搞上去,不过想加个金手指,毕竟邮票孔只能用一次,对我这种纯粹是在玩的人来说,还是比较奢侈的
钱是一方面,另一方面是,每个板子都是手焊的,都投入了精力
2.做个两个DDR的板子,因为全志提供的参考电路就是两个DDR的

说起来个问题,DDR的植锡比较麻烦,中间是凸起的,这就意味着必须要锡珠才能植上去,锡膏刮不平

EE 说:

DDR3 是不是有两种电压规格(1.5/1.35?)?还是我记错了,建议对一下DS
另外,全志有一个phoenix xxx什么的测试烧机工具是吗,我听过没有用过,也建议试一下
还另外,有试过换电容吗
又另外,换其它卖家的DDR试一下

我画过两次,都还算顺利,看来是运气好

最后,,是芯片发烫问题没有解决,就没有继续整了

有一个测试工具,我在uboot里面翻到了clk的配置了,今晚回去先试试降低CLK

#24 Re: 全志 SOC » 自制全志H3核心板 » 2020-12-21 09:57:04

raspberryman 说:

楼主软硬通吃,佩服佩服,试着给uboot的dram和cpu降频,看能不能稳定。

是的,我也是这么想的,所以后面我翻了一下uboot源码,但是没找着源码内设置CLK的地方,make menuconfig有个设置CPU速度的地方,我从1G改为480M
友善之臂的uboot有两段,看打印信息,第一段CPU确实改为480M了,但是第二段不知道从哪,又改成了1G
另外目前打印信息上看,DDR在UBOOT下是408M

这里有两段,是因为,第一段在找EMMC,我没焊接,他跳转到了另一段uboot,从SD卡启动
我修改源码,改了EMMC启动下的CPU速度,但是SD卡应该有另一个源码,又被搞回去了

板子能跑起来
但是很不稳定,经常启动失败
要么卡在start kernel,要么卡在启动一半
镜像没问题,用nanopi zero已经测试过了,问题肯定是我画的板子上
028.png

最开始还是以为是焊接问题
我重新换了CPU和DDR,发现现象都是一样的
所以焊接应该是靠谱的
这是我H3已经用完了,重新值锡
029.png
吹完之后,是这个样子
031.png
整理干净之后,看起来还算是比较均匀的
030.png

测了一天,定位到复现方式
032.png
左边是CPU,右边是DDR,用手指按黄色的位置,能让板子跑起来
检查这部分的走线情况
从靠近DDR开始,从上往下,分别是
SDQ7
SDQ3
SCKE1
SCKE0
SBA0
SBA2
033.png
034.png
目前我能想到的问题是,sdq3和scke1直接,是不是要用地隔开,不过这应该问题不大,我走线的距离都是3倍线宽的,有干扰,但应该不是很大才对
还得再想想

反复插拔发现出现了多次和DDR通信失败的情况
分析这个问题应该和DDR有关系
1.电流变大,说明板子上有个什么东西跑起来了,现在板子就两个芯片,一个H3一个DDR,电流小的时候,要么DDR工作不正常,要么H3工作不正常
2.温度会影响状态,说明温度导致某个参数发生了变化,网上有说虚焊的,热胀冷缩导致虚焊接触更好,感觉这个可能性不是很大,因为我手摸着电路也时不时能让板子起来,30多度的体温能让焊锡热胀冷缩,可能性有点低
3.有影响的应该就两个方面了,要么走线不合理,有干扰存在,不过想想这个可能性应该不高,我手不碰,单独加热是能行的
4.最终分析认为,问题应该在阻抗上面去嘉立创官网查参数
021.png
020.png
按订单的结果,现在DDR地址和数据走线上阻抗应该在80ohm左右
一般要求DDR数据和地址上是50ohm(±10%).差分是90~100ohm。
很明显阻抗是不合要求的

今晚回去改板子,再来一次

终于过了startkernel了
发现一个怪异的现象,板子需要加热,才能跑起来
而且温度越高,高到烫手的程度,才能走过start kernel
电流也和温度成正比,温度越高,电流越大

昨晚回来,板子没跑起来,我查了下原因,发现之前的电源还是不太正常,像那个1.2V跑出了1.28
根据实际情况,调整了一下电源部分

回复: 86

这个计划已经酝酿了一段时间了,最开始并没有明确的目标,使用哪个芯片。
考虑过全志的V3S/A33/H3,NXP的IMX6还有瑞芯微的芯片。
最终选定使用H3.原因如下
1.价格相对来说便宜点
2.支持HDMI,不想买屏幕,买了也是浪费,用几次就吃灰了
3.资料相对来说多一点,淘宝上有几款这个片子的产品

20201114
开始上手画板子,先走DDR
2@VMX7SK[$ODMGYDUK2QMP0.png
距离放的有点远,怕后面的线走不下去
准备用四层板,6层不想搞,主要是我不想花太多钱,贫穷使我放弃了6层

20201115
把线基本扯通
none.png
元器件位置基本上就这样了
四层板就这里不太好,线一多,留不下一个完整的地平面

20201120
最近公司加班比较多,没时间搞,歇了几天,继续画板

优化一下走线,把没扯的线继续拉通

20201121
差不多了,准备打板去
