Is there anyone that can support me with enforcing GPL compliance on company that ships product with binary u-boot? Or did that in the past?
We can try.
They're "made" (branded is probably better word) by local companies, and my guess is that most of them is violating GPL.
Guesses are not good enough in such legal affairs.
I can't do much myself (except for nagging them for source code), as it's not my copyrights that they're infringing.
So did you contact the vendor and ask for the source code? And did they answer, and what exactly?
Best regards,

Hi there
Has there been any progress on this GPL non-compliance issue?
Similar products as mentioned by the OP are also available in the USA. I have purchased one of them, a HomeWorX HW-150PVR "manufactured" and distributed by Mediasonic, which seems to be a DBA for Major League Global Enterprise LLC, 16968 Gale Ave., City of Industry, CA 91745, USA. A product of identical functionality is the iView-3500STB "manufactured" and distributed by Wiltronic Corporation.
Both products are set-top boxes with ATSC TV tuners and a USB port for recording and playback of content. The main board has a MS7816 SoC made by MStar Semiconductor of Taiwan.
On startup the onboard serial port outputs:

Hello U-Boot

This version of U-Boot installed in the product seems to have been significantly enhanced by MStar. The `help' menu is:

The HomeWorX product documentation and their website do not mention anything about GPL software or the GPL. Several weeks ago I contacted Mediasonic Tech Support by email for a request of "U-Boot and any other GPL source code. For the first email, I received a response of "will pass your request to Design Department." A follow-up inquiry was ignored.
This week I posted a public request for the Mediasonic/MStar GPL source code at Mediasonic's user forum: http://forum.mediasonic.ca/viewtopic.php?f=44&t=1820. But it seems like the forum's Admin/moderator has chosen to ignore my post.
Any advice on how to enforce GPL compliance and obtain the source code?
