I have this one found in my garage https://www.amazon.de/Paradisetronic-com-Programmierger%C3%A4t-ISP-Adapter-Programmer-Arduino/dp/B07Y3B8H91

droidbox,

The Dockstar has the standard JTAG interface. Meaning you can buy the regular JTAG header and solder it in. And use the instruction in the Wiki for the Pogo E02.

You also need to use the values from Dockstar kwbimage.cfg (compare those with ones used for the Pogo E02 in the tutorial). The only difference should be the RAM size.

You can also see rudiswiki for a quite good instruction for the Dockstar:

I found these guides to use the wrong ECC algorithm, it kinda works but you won't be able to read the nand from uboot. That's why I made another cfg file.
Btw, the USBasp has few jtag firmwares, but I don't know the actual functionality and if OpenOCD supports them.

I will give this howto next week a change

@David,

Pardon me! I forgot that part in your writeups, a long thread :)

@droidbox,

You can use either the Pogo E02 instruction or David's instruction. But do use the dockstar.cfg in davidalfa's post.

Can you share on how to put alpine linux on?
