AM335没有CAM接口,上次客户指定要用它做一个工业相机,我也是硬着头皮使用高速FIFO做出来了! 的确这个am335x没有 camera接口,所以,很多应用都不能用; 本帖最后由 NJ8888 于 2015-7-9 16:42 编辑
楼主你好,我测试IO翻转如果是连着HLHLHLHL写代码,中间基本是H(等待100ns)L(等待30us)H(等待100ns)L(等待30us)H(等待100ns)L这样,奇怪为何不能连着翻转,30us 100ns都是大致数值,用偏移190H和194H的地址操作
我出100 楼下继续 千兆网卡没用,有点浪费 100预定一块 漂亮的板子 千m网络的性能一般,能跑200m就不错了,不信,大家把跑的参数都亮出来,都看看 本帖最后由 diegoo 于 2015-7-11 04:05 编辑
树莓派2代 B型是Cortex-A7四核,1GB内存,淘宝价格18X元。楼主这个超过200元就没有意思了。
播放视频效果怎么样? COM 口搞那样,你看着不难受吗。还有,你这可用到什么行业 可以参考ZLG的定价贵了不会有人买 AM3359可以接CMOS 价格168比较合适 感谢大家提供建议!谢谢;

干嘛不上AM437x呢?芯片价格差不多吧,能接两路camera
我看是beagleboard还没有出AM437X,没得抄 别人都做过的东西, 卖价又不高,哪挣得到钱啊 板子做的不错,很漂亮,的确开发板这个东西技术支持是个头疼的事情。如果是卖核心板,这样的设计对生产要求很高,虽然成本低。核心板竞争的确比较厉害,没办法保证利润!
当年公司也做了不少核心板,DM270,DM355,DM6441,DM365,DM368,OMAP…………,ti的东西太难伺候,资料太少,arm+dsp资料太少,唉,累的很,还赚不了钱。
哈哈哈,N年前我们公司还是ti的第三方,n次ti电子展都有我们公司的东东。
说多了,罪过!
帮顶!

差不多?不会吧,价格多大?感觉至少2倍以上吧? 为什么做技术支持呢?买着大家去玩吧?哈哈,

可以参考ZLG的定价贵了不会有人买
ZLG 350 现在正在用 本帖最后由 孤独的猫 于 2015-8-21 09:14 编辑
AM3352 最近要50左右,AM437x估计 80多了 最新进展:
1,支持全新的3.14版本的内核了!
2,支持dtb了,目前国内比较早支持的!
把移植手册放上来供大家参考一下!
核心板多少钱
全新双千兆网络的am335x主板有谁要吗?
兼容BBB不?
公司在考虑用两个A8来代替以前的PPC。目前在尝试把原有的代码搬上去,基本都在BBB上完成。
现在打算做张底板,贴两个A8核心板上去(直接画板耗费较大),想找尽量兼容BBB,引出NAND总线的核心板。
PS:如果有EMC的实验报告,可以考虑直接在产品上使用核心板。 说明书上表示有GPMC,但是为毛淘宝介绍页面上没写? fengxin32 ,您好:
非常高兴与您交流!
兼容BBB不?
我们的产品是兼容bbb的,但是需要emmc启动的;
当然用tf卡做启动也可以;

您现在这个需求,我们可以满足,但是还不知道您是否有其他需求?
有时候需要综合考虑!方便的话,您加我qq:259134942,我把资料发给您,您查阅一下我们再交流;
PS:如果有EMC的实验报告,可以考虑直接在产品上使用核心板。 用tf卡启动,就可以使用nand总线(gpmc总线),因为tf接在mmc0上;
如果用emmc的核心板(emmc接在mmc1上),此时,会和gpmc冲突; szartcor 发表于 2015-10-21 21:24

对不起,这几天忙着折腾一个低成本的设备平台,很久没上来了。
我们是打算一个A8 NAND启动(EMMC的温度范围不足),一个A8 用SPI Flash启动(裸奔,不需要那么大的空间)。
两个核心板都需要有GPMC接口,我们初始化成NAND,用来连接FPGA。 您的要求,我们完全可以满足的.
我们已经测试过spi nor flash启动了;
强大啊,支持!! nice !!!不错! 跟我想象的不一样
感觉一般啊
