你好,我这有一批用CC3200的产品,现在才烧录了40PCS,就有4PCS烧录不进去的,不断要求复位,烧录软件最后显示的找不到硬件,。
检测测到硬件上的SOP2脚电压约为0.6V(3.3V供电,正常板子约为3.0V),此脚无法拉高配置为SOP[2:0]=100,无1.2V,晶振不起振。这CC3200是损坏了吗?损坏原因是什么?为什么会有这么多不良的?
gaoyang9992006:
进货渠道有问题吧,可以直接在ti.com下单购买的,直接美国发货,应该更靠谱。
Terry Han:
CC3200芯片在进行SPI烧录过程中如有无法烧录的,先用下载软件Uniflash进行Format格式化一次SPI Flash芯片,然后再次进行烧录下载程序,

回复 Terry Han:
无法格式化,不断要求复位,不按最后显示无法找到硬件。烧录过程如下,有什么方法可以避免或降低不良率吗?

Jang 你好,
1. 核查一下您的进货渠道, TI的CC3200 Launchpad每一块都是经过PLT流程测试通过的;
2. 你是使用的CC3200 Launchpad还是自己制作的板子?如果是CC3200 Launchpad,你可以更新一下板载FTDI的固件,再试一下。如果是自己制作的板子,建议检查一下你的电源,看是否稳定。
3. 当板子连接到电脑后,查看电脑的设备管理器,看有没有设备连上,若Ports没有反应,则说明是下载口的问题;如果Ports显示设备连接正常,而只是SOP2脚电压不正确,则需要检查你的硬件电路和CC3200的电源是否正常。
HENG WU1:
我们原来也是同样的问题,应该是电源供电不稳造成的,请检查一下供电系统,最好使用示波器观看下电源在在下载时的波形,芯片一般不会有问题的,不要老是怀疑芯片质量问题,很可能是硬件设计不规范造成的。硬件确定没有问题话请检查下下载操作步骤。步骤在附件中。还有一点忘了说,sop电路一定按照官方提供电路,不要想当然的更换电阻,会造成下SOP配置不正常的现象,不能按照用户的设定进行引导。

您好,请问您关于CC3200的问题解决了吗,我遇到类似的问题!确定了是您的芯片有问题吗?
