In this Article we will explain all about Vivo V7 Plus Edl Pinout / Edl Test Point. eMMC and eMCP memory are the standard in today’s smartphones, and the ISP practice enables examiners to directly recover the complete data without removing the chip and destroying the device. In-System Programming (ISP) allows communication to take place with a target chip without the need to remove it. The main advantage of this method is the possibility to communicate with a target chip eMMC or eMCP bypassing the CPU. It brings higher speed for data extraction compared with JTAG but it requires great soldering skills. ISP applied to forensics, is the practice of connecting to an eMMC or eMCP flash memory chip for the purpose of downloading a device’s complete memory contents.

What is ISP Pinout ?
ISP means “In-System Programming”.In-System Programming (ISP) allows communication to take place with a target chip without the need to remove it. The main advantage of this method is the possibility to communicate with a target chip eMMC or eMCP bypassing the CPU. It brings higher speed for data extraction compared with JTAG but it requires great soldering skills. ISP applied to forensics, is the practice of connecting to an eMMC or eMCP flash memory chip for the purpose of downloading a device’s complete memory contents.
eMMC and eMCP memory are the standard in today’s smartphones, and the ISP practice enables examiners to directly recover the complete data without removing the chip and destroying the device.ISP benefits the examiner who faces the challenges of tightening budgets, yet wants to expand their expertise in retrieving evidence from locked smartphones. A cost-effective technique, ISP provides examiners with the same results of a chip-off at a lower price-point.
Why do we need ISP Pinout ?
Just Like “Joint Test Action Group (JTAG)” there are specific contacts that will be of interest to the examiner. But unlike JTAG, the contacts are directly off the chip BGAs and do not go through the processor. Acquires data much faster than JTAG, enabling examiners to process more phones faster.
- CMD
- CLK
- DATA0
- GND
- VCC – Voltage Supply for Core (3,3V)
- VCCQ – Voltage Supply for I/O (1,8 – 3,3V)
The purpose of each signal is as follows :-
CLK : Clock signal for synchronization.Each cycle of this signal directs a one bit transfer on the command and either a one bit (1x) or a two bits transfer (2x) on all the data lines. The frequency may vary between zero and the maximum clock frequency
CMD : This signal is used to send the Host’s command and Device’s response.
GND : VSS is the Ground for Core & VSSQ is the Ground for I/O.
VCC : VCC is the Power Supply for Core.
VCCQ : VCCQ is the Power Ssupply for I/O.
