UUU到底怎么用,快崩溃了

在贵司买了个6ULL(6y2dvm05aa)的开发板,之前用MFGTOOL烧写程序。uboot下面网卡灯是可以亮的,起动后,发现网卡两个mac地址是一样的,网卡总是link not ready。后面我找啊找,终于发现有可能是网卡芯片版本(A2改A3)的问题,需要打个补丁,不会玩。无奈请教厂家,现在又教我用最新的UUU烧写程序,为什么我就烧不了呢?UUU和文件夹还有命令.png

Thanks, Joan! But I can't resolve the problem by the instruction you provided. I use the following one, and it seems working well:

uuu -b emmc_all u-boot-imx6ull14x14evk_sd.imx fsl-image-validation-imx-imx6ul7d.sdcard

So is it OK?

Now, another problem is encounterd. I know, if the USB-UART device is plugged to the USB slot, the name will be given of ttyUSB0, and it's shown under the folder of /dev. And there are 5 serial ports on my development board, but it just shown the ttymxc0 and ttymxc1, and the ttymxc0 is also the one connected the terminal. And my question is how to show the other 3 serial ports. I'll appriciate if you can help me.

It's the serial instruction screenshot for reference(MCU:imx6ull6y2dvm05aa).

Best wishes!

Seaman,
