我也画了一个,做了等长,没做阻抗,还不知道能不能跑。这种板子怎么做阻抗呢,线宽基本上没法再调整了,我用的线宽是4.5mil,调粗了走不出来,调细了对板厂要求又高

可以跑,无非就是速度上不去,你找到跟时钟有关得地方,速度放低点就好了

最近这一两年,AI搞得也是比较火热,3588这个性价比,说实在话,不是太好,千把块的核心板还不如买个手机摆着,估计瑞芯微自个也看到了问题,出了一个3567,综合来看,性价比还可以,感觉还是有市场的,业余期间搞一下

花了两个礼拜,断断续续的搞,终于是把线拉通了,接下来把等长和差分捋一下,再把电源好好扯一下,就打个样试试看
目前主要问题就是个头有点大,不过考虑到是首版,先把线走通,然后慢慢缩小吧

关于接口,当时考虑了邮票孔,金手指和BTB,各有各的优缺点,也是纠结了一通
邮票孔的话,这个芯片出线多,做太多的引脚核心板就很大了,不太合适
金手指在考虑内,不过类似DDR的那种,也是比较长
最后选择了BTB,不过回头贴片是个值得担忧的问题,就怕歪了

ps:这个月感觉有点克我,干啥啥不行,也是**了

#6 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

#13 Re: 全志 SOC » 有哪位兄弟V3S做过-40度运行测试啊? » 2021-01-11 17:35:22

除了V3S,你还应该看看其他的元器件,是不是扛得住

#14 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

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

#24 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

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

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

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

吹完之后,是这个样子

整理干净之后,看起来还算是比较均匀的

测了一天,定位到复现方式

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


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


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

#34 Re: 全志 SOC » 自制全志H3核心板 » 2020-12-10 23:37:14

20201210

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

现在是凌晨0:00

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



串口上面已经有数据打印了
证明芯片已经在运行了,但是卡在start kernel,明晚在继续找问题

发现少了一个料

漏买了,赶紧淘宝补一个
现在就把手上的板子拆了个芯片先用着

焊接完成,测试电源




3.3V差了0.05,1.2V高了0.08
应该影响不会太大

之前说要拍视频的,因为手机不太好录制,缺个手机支架
再就是焊接好像不是很麻烦,几分钟就吹上去了,就没录制视频
EMMC后面再说,先把H3和DDR搞上去

今晚下班,飞线测试能不能启动

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
[img]/files/members/5522/2@VMX7SK[$ODMGYDUK2QMP0.png[/img]
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

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
[img]/files/members/5522/3X6Z40A4F[NC641FY8[N[51.png[/img]

过孔小了,要加钱。。。。

想都不想,直接放弃

20201127
不能放弃,再来一次,把过孔整大点

前面画过一次,大概知道会有哪些地方会出线,把距离调短点

20201128
前面是搞的座子对插的,想了想,还是搞成邮票孔算了

先把线跑通,元器件慢慢放

20201129
元器件都扔上去了


大概就这样了,继续搞,争取明天审核完

唉,地被搞得乱七八糟,自己都看不下去了



20201130
发出去打板,审核成功,开始备料
