First, let’s take a look at the data file format of the RT809H’s eMMC chip as follows: The part circled in red is variable, and users can name it themselves. .BIN, .BIN.part1, .BIN.BOOT1, .BIN.BOOT2, .BIN.EXT_CSD and other file extensions are fixed; if they are not, the programmer will not recognize them or the software will … Read more
Background:Some customers have reported that certain Hisense motherboards using H26M62002JPR, H26M51002KPR eMMC chips prompt a timeout error during reading, preventing read/write operations. The analysis indicates that the issue is due to non-standard eMMC. Hardware Support:This version is compatible with previous ones; simply transfer the socket head and 25 chips to the new PCB. Software Support:Versions … Read more
eMMC, or Embedded Multi Media Card, is defined by the MMC Association. The concept of an embedded multi-media card may be unfamiliar to many. Let’s start by understanding it literally. Since there is an embedded multi-media card, shouldn’t there be a multi-media card? Exactly, you are correct. Moreover, there is a type of card that … Read more
In 2016, the configuration of Android phones was upgraded to a new level, featuring the Snapdragon 820, 4GB of RAM, and storage capacity soaring to 128GB. A small detail here is that it adopted UFS 2.0 flash memory instead of the previously popular eMMC 5.1. So, what exactly is UFS 2.0 flash memory? Why are … Read more
1 What is eMMC eMMC stands for embedded MultiMediaCard, which is a standard for flash memory cards that defines the physical architecture and access interface and protocol for storage systems based on embedded MultiMediaCard, specifically established and published by the JEDEC (Joint Electron Device Engineering Council).It is an extension of MMC with advantages such as … Read more
The socket comes in two versions, both offering the same functionality. The framed version requires manual swapping of the locator frame when encountering chips of different sizes; the frame-less version directly utilizes solder balls and base positioning holes, eliminating the frame-swapping step. Super positioning without a locator frame: for chips of different sizes, positioning is … Read more
