Some facts about the board: Boot0 is V4.0.0. DRAM is 1GB DDR3 @ 672 MHz. eMMC is 8GB (7.32 GiB). AXP818 is a PMIC & audio codec combo. AC200 is a audio codec (unused here), TV encoder, ethernet PHY and RTC 4-in-1 chip. USB0 (OTG) and USB1 (EHCI/OHCI) are routed directly to the 2 USB ports. That means no actual OTG, only host mode. The board (and schematics) say this is an H8. However I won't be removing the heatsink to verify. I don't recommend it either. It is quite warm just idling. That said, the A83T has the same packing as the H8 (BGA 345), though I have not compared the actual pin signals. Kevin, Shuge, do you know if the 2 chips are actually the same? 請問 A83T 和 H8 是一樣的晶片嗎? 提供給我們的板子上是印 H8， 但告知我們是 A83T 的原型機，讓人不是很有把握。 The board runs a customized Android system. Not sure if FEL mode or Android fastboot would work on this board. If not, it's going to be hard to mainline without U-boot support. UART0 is the 5 pin-out next to the WiFi module and AXP818. It shares the same pinout as the micro-SD breakout, or the A80 Optimus. Note that the onboard OS muxes UART0 onto mmc0 instead. :| ChenYu > I'ld like to start a thread about the planning of the mainlining of the A83T. > > If there are any other topics not directly related to this thread, > please start a new thread. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
