Re: XC5000C 0x14b4 status
IMHO, the best is to get the latest firmware licensed is the best thing to do. Does that new xc5000c come with a firmware pre-loaded already? I've got firmware here that is indicated as being for the xc5300 (i.e. 0x14b4). That said, I am not sure if it's the same as the original 5000c firmware. Definitely makes sense to do an I2C dump and compare the firmware images since using the wrong firmware can damage the part. I'm not against an additional #define for the 0x14b4 part ID, but it shouldn't be accepted upstream until we have corresponding firmware and have seen the tuner working. Do you have digital signal lock working with this device under Linux and the issue is strictly with part identification? Hello. There are new details. My assumption, that such behaviour of IC can be because of an old or incorrect (for that HW) firmware, was wrong. It does not matter which FW version we use. With a fresh (beginning of 2015) media_build, even with an old firmware, RF tuner always and stably returns status 0x14b4. Also it's stably detects an already loaded firmware from another instance of the driver (analog part initialisation). And there is no i2c errors. With an old media_build from beginning of 2014, there is some problem with detection of already loaded firmware, there is i2c errors, and it gives the 50/50 status either 0x1388 or 0x14b4. My mistake I didn't checked a fresh media_build before. So, the only thing we need is to add an additional #define for the 0x14b4 part ID to a driver's code, as I wrote before. If you have any more questions, please ask.

Here is a link on a chinese site with datasheet for xc5100. http://wenku.baidu.com/view/7f92f3fe700abb68a982fb96.html If you look at it, after reading Product ID we also should receive 0x14b4 (5300 decimal) I'll try extract a FW from a Windows driver and will share results, in case of success.

Re: XC5000C 0x14b4 status
Correct. These are not parts that have any form of default firmware in their ROM mask (i.e. not like the silabs or micronas parts which have a default firmware and the ability to patch the ROM via a software loaded code update). The firmware must be loaded every time the chip is brought out of reset or it won't work at all.

Re: XC5000C 0x14b4 status
It's not new IC. It's XC5000C. Maybe i was interpreted wrong. As I have understood, such behaviour can depends from FW version. HW vendor says, that with his latest FW he always gets response 0x14b4. Ah, so you're running a completely different firmware image? Well in that case that would explain the different response for the firmware loaded indication. No no no. I used a FW image, which was taken from KernelLabs site, and it was intended for use with XC5000C. And partnumber of IC was XC5000C ( I have opened RF shild to check it) Not a 0x1388. And I think, that these ICs still come without pre-loaded FW. HW vendor also didn't says anything about FW pre-load possibility. Correct.
