EBAZ4205 Bitcoin miner board - For sale (listings)

I recently almost bit on a listing that I thought was for $15 (the actual price was $30). The trick is that the picture they show may not be what you think you are ordering! Beware on AliExpress as this seems to be a trick that is being used more often these days. They show you a picture, but there are several items you can select.

Here is the description in the listing. Very likely some google translation (or other) from the Chinese, but who knows:

Friends and see many places has EBAZ4205 the zynq boards at a lower price, but suffer from no data into the door, the lamps are on BBS, complex uboot kernel DTS rootfs no one do. Novice is not expected to do, veteran too lazy to do, so I just take a few days to transplant, sorting out. I'll give, give to introduction to the altar of friends made a set of complete information, including vivado U - the boot kernel debian source code, compiled files. I am your welding a TF gets stuck up, get on R2584 welding to R2577, thus became a TF card, easy to burn program, so the compiled are TF card program, need to use the nand under the changes themselves. This code board peripherals are normal, can be normal in the UBOOT save env to TF card, network normal communication, TFTP normal function.The kernel is, debian network functions are normal, can be apt at will.IO W13, only two existing W14 LED lights, other IO need to yourself.

ZYNQ is a good thing, recommended into the pit, hey hey.Used AT91SAM9X35 EP4CE10, match XC6SLX16 IMX6, match EP4CE6 raspberries pie, is all some collection and control of the class, really is not convenient, communication between the chip and the speed is limited, if use external bus, have taken up too much of IO again, often conflict and peripherals pin. Made the ZYNQ two events, and later found really good things, a train movement acquisition device, an 8 axis robot control card, really good internal AXI bus and high-speed simple, tie-in use very awesome, hang up a pile of things, very convenient to extension and the price is not expensive, now really fall in love with this movie, later again the ARM + FPGA project must choose this. So take the time to do this time the hope to help more friends.

Cut the crap, data, because the debian file system and the kernel code is bigger, so only to the cloud.

The SD card first in two area the first FAT the second corruption is the most common method of partition, FAT a 100 m will be enough. In the image directory bootfat. Tar..bz2 decompression on the first FAT partition rootfs. Tar. Gz is debian file system, into the second corruption partition.Then start is OK.

Source code is in the cloud, you go to the study, the board can be out at the foot of the table, don't need xilinx simulator can play.
