[本文简介] About this resource guide

There are plenty of resources in TI Website and AM335x Wiki. This resource guide means to make it clear for you to get the entrance quickly without reading so many documentations first. You can go through these resource links and get the concept for the device / platform quickly.

[硬件设计资源] H/W design resource

TI provides a rich set of documents for hardware design reference. Please refer to AM335x Hardware Design Guide.
1.  [芯片资料] AM335x chip documents contain the latest device User Guides(TRM), Data sheet (DM), and Silicon Errata(Silicon bug and the workaround). 
2.  [评估板] TI provides functional verified reference boards EVM for your reference:
         a. AM335x GP EVM : AM335x General-Purpose EVM .
         b. AM335x Beaglebone : AM335x Beaglebone.
         c. AM335x StarterKit : AM335x StartKit.

         d. AM335x Beaglebone Black: AM335x Beaglebone Black

         e. AM335x ICE: AM335x ICE   Note: ICE V2 schematics, pls refer to here.
3.  [原理图设计] AM335x Schematic Check List

15. [NAND Flash 选择] There are two kinds of NAND flash supported for AM335x NAND booting.More information for NAND flash selection.使用NAND flash启动时,对NAND的选择有限制。AM335x支持以下两类:
     (1) 支持ONFI的NAND FLASH
     (2) 在TRM的Table 26-13. Supported NAND Devices中能够查到Device ID的NAND FLASH

16. [NOR FLASH启动设计注意点] Refer to the documentation post in deyisupport

17. [EMMC芯片启动注意事项] AM335x的MMC0和MMC1都可以支持EMMC芯片作为启动介质,如果是4G及以上容量的EMMC芯片,需要接到MMC1上,具体请参考TRM的26. 

18. [USB OTG 设计] AM335x OTB VBUS电路设计的注意要点

19. [Ethernet PHY 电路设计与调试] AM335x 有两个10/100/1000 EMAC,可以外接PHY芯片扩展2个10/100/1000网口。与PHY连接时,支持MII/RMII/RGMII接口。


20.[Touch Screen的选择与设计] AM335X 触摸屏的硬件连接及Linux驱动

[软件设计资源] S/W design resource

TI has rich reference software for customer development including OS platform (Linux, Android, WINCE and RTOS) and non-OS platform(StarterWare). For software design, please refer AM335x Software Design Guide.

OS platform:

  • 3. [Windows CE7]
    TI Windows Embedded Compact (WEC) 7.0 BSP can be downloaded from here.
        Hand Book :
  • 4. [RTOS]
    The overview about RTOS supported by AM335x can be got from here. For the 3rd party RTOS, you need to contact the Vendor directly.

Non-OS platform:


  • [QT]QT is a cross-platform applications and UI development framework, Building QT.

Other Software:

  • [PRU software package]

PRU Software Package. Please note that this is intended for “do-it-yourself” users and is not officially supported by TI.

[工具] Tools & Utilities

Maybe some additional utilities are needed for downloading, compiling, and development.
