v11好像变成白色的了，我们公司用的V9。确实有点贵，自己买的使用ST-LINK

这和以前的大不一样，以前的好像是atmel的

花了几百块，好象现在也没有鸟用，就整瑞萨的才有用。

要求不高，能烧就行

习惯了ST的link，感觉jlink就是在一些脚本调用刷写的时候方便点，然后价格是真的贵

 

最后建议赶紧退货

退不了啦，留着吧，有时可能要用得上，关键要买时，物流还慢。

各位大佬，想问下显示这段代码怎么解啊，给其它MCU烧不了都

提示你检查一下硬件连接。

我也碰到过，就是逐一核对一下接线。

首先我不明白你们说用的正版的jlink不发热为什么不提一下硬件版本，听说v10 v11 v12用的是同一个mcu，不同版本的硬件也不一样，发不发热不应该是相同方案的硬件进行对比吗。其次我的D版JLink Plus V11用的和版主的同一个方案，会有发热的问题但是商家有给配散热片，感觉起来还行。去掉散热片确实会很热一些。至于为什么会热，请各位移步到NXP官网去看看他的内核结构（M4加M0+双核）双核放热比单核大个人认为属于正常现象，毕竟单核M4的stm32f4我做DSP的情况下也会非常烫手的。同时，建议买D版V11的用户注意一下我买的plus 无法更新固件因为官网没有相应的固件版本，请各位周知

其实程序都是一样的，就是官方有没有授权。
