I have some tests on the bug boards today.

Address can not be assigned because of HWAddr is not correct. HWAddr is hardware mac address.

It is FF:FF:FF:FF:FF:FF

eth0 Link encap:Ethernet HWaddr FF:FF:FF:FF:FF:FF

Use ifconfig to setup that address and bring up eth0 success.

ifconfig eth0 hw ether 46:9B:94:0A:E6:71
ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up

ifconfig eth0.1 hw ether 46:9B:94:0A:E6:71
ifconfig eth0.1 192.168.1.101 netmask 255.255.255.0 up

ifconfig eth0.2 hw ether 46:9B:94:0A:E6:71
ifconfig eth0.2 192.168.1.102 netmask 255.255.255.0 up

And now in ifconfig ethernets are all up.

ifconfig wlan0 192.168.1.103 netmask 255.255.255.0

setup ip for wlan0.

Now the ifconfig result is same as the normal one. But iw dev wlan0 scan has nothing returned, wireless module still dose not work.

Another try is to call:

/etc/init.d/firewall stop
/etc/init.d/firewall disable

firewall is stopped, still dose not work.

This bug is not easy to locate now. I guess this must have some connection with hardware, now I have to check the ethernet driver to see what will cause it failed to start. Lucky me still have one board work. It will be a long way to find out the problem.

After get out that RT5350F from the board, I find the solder is normal. Every ball touched its pad, so this might not be solder problem.

I have to check software again. Get boot log from normal board and the bug board again, compare the two.

normal one:

Here is that problem:

ifconfig: SIOCSIFFLAGS: Cannot assign requested address

eth0, eth0.1, eth0.2 can not bring up because of  “can not assign requested address”.

Today I got a weird problem.
I soldered five boards but only one of them wifi did work, two of them wifi part did not work, two of them did not work at all.
That failed two are BGA problem. I used too much paste, make it short connected, so that two failed.
But why the other two did not work?

I think that is solid problem, tomorrow I will get off that BGA chip and then we will know what happened.

But my computer is able to connect to it!

Miracle!!

In fact, even I did not connect any antenna to the board but there is a very very short “antenna” on board. And my computer is just 1m from that board. Then, it connected. LOL 😀

Today I use a infrared thermometer on the RT5350F chip, the temperature is 68~70°C…

On the datasheet its working temperature is -10°C~55°C…

How is this possible? I did not run my customised application yet. T-T

Another good day!

I can not wait for the new 2.2nH and 2.7nH from chip reseller. So I just get two 2.7nH from my old board then solid it onto VoCore v0.3, now it works. Fantastic!

Here are some screen captures from my board:

ZakeNetwork is a HiFi router, the distance from VoCore is about 8m(-70dBm), another is about 1m(-40dBm).

Using command iw dev wlan0 scan | grep -E ‘SSID|signal’

Pictures from the new wifi valid VoCore v0.3. 🙂

vocore.bin size 2883588(0x2c0004) => download here. In bootloader, use loadb command to transfer it from local to vocore memory. Then call cp.linux 2c0004 to copy it to flash. If there already exists old linux, call erase linux to delete old one.

The offical bootloader loadb command might not working. We have to change some code on its uboot. Details here: https://forum.openwrt.org/viewtopic.php?id=44472

VoCore v0.3 solid is done 🙂 Here is the picture.

不再有飞线的和平世界 ^_^

It is night, a little dark.

I am lucky, the first time I connect it to 3.3V, success into boot loader and linux system.

Bad news is wifi do not work at all.

Good news is I just find the problem in two minutes. There are two inductance on the antenna, one should be 2.2nH and another should be 2.7nH, but the real one I solid onto the board is 2.2uH and 2.7uH…Thousand times bigger than my schematic value. The careless seller send me the wrong inductance. I have to wait them send the right one and test wifi part later.

3.3V/0.3A = 1W: run linux with wifi on/ethernet on(two ports).

3.3V/0.25A = 0.825W: run linux with wifi on.

3.3V/0.15A = 0.495W: run linux with wifi off.

Finally VoCore v0.3 PCB comes to my home today. Now there is no jump wire anymore.

So happy, now I have a board that I have full control on it.

I have a raspberrypi, I can not full control it and I have to buy a 30USD camera, that is expensive. I want to DIY one, but camera interface is not opened. I really hate that, I just want to control every corner of my own board. That is one important motivation for me to make VoCore. I think if you want every one to use it for study or learn programming, it is better to open them all.

But for my module, in my further plan, I will make a camera based on OV2640 or OV3660 which supply JPEG format output, the camera price will be under 10USD.

Next version should be the final version, v0.4, in that version I will use “Semi-hole technology”(searched from google, in Chinese it should be 半孔工艺) to make the board smaller. Now its size is 27mm x 27mm, a little bigger than 1RMB coin(25mm). Next version it will be 24mm x 25mm with a on board Ceramic Antenna, but I am not sure about that, I need to test on 0.3 first to make sure ceramic antenna works well on my side.

After wifi test/GPIO test and other test is done from my side, I will make about 100p, and try to sell it at 10USD on taobao/ebay. Hopefully then more people will help me develop it and make this one better or even smaller. Software and hardware will be all open forever. 🙂

This module, in some situation, it is better than arduino for study embed.
