iriver T-series flash-based players

[linuxstb]

The CPUs are SA58450X01/02 (not 480).

Info from Samsung is here:

Googling for SA58450X01 gives a lot of hits, including iriver references with photos of dissected players showing the CPU, but no sign of a datasheet so far.  These chips contain a 200MHz ARM9 core, and a DSP consisting of a CalmRisc16 and 24-bit MAC unit.

Merged related topics. Please, read a little more thoroughly before saying "I don't see any mention of them here." iRiver T30 was even on the front page of New Ports.

A little bit more info.

Many different firmware upgrades for the T-series are available here:

These are ".HEX" files and can be decrypted/encrypted using the tool here:

However, it appears that the datasheet for the Samsung SA58450 isn't publically available, so a port would have to be based solely on reverse-engineering the existing firmwares.

I only know they use the SA58480X01 (T10) and SA58480X02 (T20) ARM9 CPUs from Samsung.

Not SA58480X01. This is SA58450X01. And info about this chip available at http://www.samsung.com/products/semiconductor/SystemLSI/DigitalMedia/OpticalASSP/OpticalPlayer/MP3/SA58450/SA58450.htm
