Hi all,
I've pre-ordered my helios4 and was so excited to finally receive my new NAS after a few months of waiting. I love this project and want to see this project to grow and maybe inspire others to create similar projects as this one.
That said, I was really disappointed when I finally started my board and realized that the UART to micro usb was broken when I plugged it in my computer. No USB device is at all recognized(on linux nor on my mac). At first, to eliminate any potential problems, I tried at least 6 different micro usb to usb cables thinking that a cable could be broken... it happens some time. With all 6 cables tried, never did I get my computer to detect a USB device plugged in.
To continue my great adventure, I soldered a 3 pin header on the UART ports of the board since I have a UART to USB cable at home. Once the pins were soldered on the board, with great excitement I booted the puppy to see if it fixed my issue. It fixed only half the issue. I now detect the USB device andI can now see all tx leaving the arm board however the rx seems to be broken. I get to the login page but can't type anything. Well that sucks. I was hoping the issue was between the UART and micro USB controller but I was wrong. Maybe the issue was with the rx all along and the UART to USB controller just don't work when either rx or tx is not working(this is just a guess). The issue is now more uphill than I thought and I won't be able to troubleshoot this on my own since I am no electronic engineer.
So now, I have a brand new board but with only tx working but not rx so basically I am at a loss here.
This looks like a manufacturing issue. Am I the only one who has this problem? This is part of batch 3 helio4.
Please let me know if you ever went through something similar or if you have an idea how I can fix this.
Any help would be appreciated and if others from the same batch has this issue, it would be great to report it rather to leave it at a loss.
Thanks
