Everything you need to know about eMMC Protocol & debugging eMMC Protocol
What is eMMC?
The term eMMC is short for “embedded Multi-Media Card” and refers to a package consisting of both flash memory and a flash memory controller integrated on the same silicon die. The eMMC solution consists of at least three components – the MMC (multimedia card) interface, the flash memory, and the flash memory controller – and is offered in an industry-standard BGA (Ball Grid Array, right) package.
What are the benefits of eMMC?
Smaller than a typical postage stamp, the tiny footprint of eMMC makes it ideal for many electronic devices, including smartphones, small laptops, smart TVs, wearable technology and smart home appliances. The “embedded” part of the name comes from the fact that the storage is usually soldered directly onto the device’s motherboard, so it is not removable nor displaced easily. eMMC storage consists of NAND flash — the same tech you’ll find in USB drives, SD cards, and solid-state drives but just packaged differently.
Beyond its use in consumer products, eMMC is rapidly being adopted in many other embedded applications, such as Single Board Computers (SBC), robotics, medical devices, automotive, networking and building control devices because of its compact size, low-power consumption and numerous enhanced features. With the rapid growth of the IoT market, eMMC is finding its way to newer applications.
How to debug eMMC?
SD Protocol Analyzer, SDIO Protocol Analyzer, eMMC Protocol Analyzer (PGY-SSM) are the Protocol Analyzers with multiple features to capture and debug communication between host and design under test. PGY-SSM Protocol Analyzer supports SD, SDIO and eMMC for data rates up to 200MHz DDR mode. PGY-SSM is industry’s first eMMC protocol analyzer that supports version 4.41, 4.51, 5.0 and 5.1 specifications.
Features of Prodigy eMMC SD SDIO Protocol Analyzer
Comprehensive Protocol Analysis
PGY–SSM Software provides the industry’s best protocol analysis capabilities. A simple-to-use interface reduces the complexities and time for protocol debug. Time stamped view of decode listing provides a complete view of protocol activities between host and device. By clicking on selection prompts, the user can get the decode of arguments, CSD, CID registers, data activities and more [detailed view]
Protocol Data Capture & Trigger
PGY-SSM Protocol Analyzer has powerful protocol aware trigger capabilities allows capture protocol events at specific events. PGY-SSM supports simple and advanced trigger capabilities. PGY-SSM can trigger specific command, response, CRC error condition. Advanced trigger capabilities allows sequential trigger condition to capture protocol data after a sequence of events. In Auto mode, data is captured on pressing the RUN Button.
Protocol data capture duration is controlled by manual stop or setting the capture duration. Manual stop offers flexibility of set protocol data capture by visual activities in DUT. In time duration user set data capture in secs to 3 to 4 hours. During the capture mode, protocol data is continuously streamed to host system hard disk drive to storage.
Analytics
Analytics features quickly provide insight into protocol activity without going through the complete protocol activity.
Card / Device Information
Card/Device Information provides decoding of register argument of device. Now the user no longer needs to manually decode each register value.
