Resources for Qualcomm MSM722x: MSM7225, MSM7227

Qualcomm MSM722x processors – part of MSM (Mobile Station Modem) series – are mainly used in mobile phones and to a lesser extend in tablets such as WellCoM A800.

You won’t find any proper documents or information in Qualcomm website (see Qualcomm MSM page) except the following description:

Qualcomm’s Mobile Station Modem™ (MSM™) chipset solutions enable cost-effective mobile handsets with advanced capabilities that leverage 3G technology yet minimize development time. Offered on four discrete platforms for tailored functionality, each chipset is integrated with a select set of features from Qualcomm’s multimedia suite of applications to enrich the user experience while maintaining cost-target objectives.

So if you plan on developing on that platform, you’ll need to visit Qualcomm developer website to get most of the information you’ll need.

There are two chipsets with similar characteristics.

MSM7225

The MSM7225 chipset includes a 528 MHz ARM11 processor with a floating point unit (FPU). A 400 MHz modem processor, 320 MHz DSP, hardware-accelerated 3D graphics, integrated Bluetooth 2.0 and GPS capabilities, a 5-megapixel camera and 30 fps WVGA video encode / decode are also included.

MSM7227

The MSM7227 chipset includes a 600 MHz ARM11 processor with a floating point unit (FPU). A 400 MHz modem processor, 320 MHz DSP, hardware-accelerated 3D graphics, integrated Bluetooth 2.1 and GPS capabilities, an 8-megapixel camera and 30 fps WVGA video encode / decode are also included.

You can get the full details for MSM7227 on Qualcomm developer site

These processors are supported by 3 different operating systems:

You’ll also find development tools for each platform on the developer website.

For Android platform, check out http://developer.qualcomm.com/dev/android/tools where you’ll find Adreno SDK and Profile (Required for OpenGL development), AllJoyn SDK (Social apps devlopment), misc. development tools, presentations, demos (with source), etc..

You may also go to Qualcomm Android Forum, although it is not very active.
