J-Link JLINK V8+ ARM USB-JTAG Adapter Emulator

(1) Improving the SWD interface circuit, the use of counterfeit JLINK V8 JTAG debug debug mode can be normal when debugging CORTEX-M3 core chips will not use SWD functionality, V7 hardware SWD part with the V8 not the same, if forced to switch to SWD mode, JLINK the main chip will be destroyed!

JLINK V8 interface circuit using two-level converter chip, using a level converter chip will be fake V8!

(2) V8.0 using two-color LED can indicate more work status, V7.0 only an LED indicator light.

(3) To optimize the firmware structure and function of the firmware upgrade bootloader area to move to double the size of the application area Easy to add new features

(4) Support for ARM11 better and faster than JLINK V7, is the first choice for ARM11.

Other Hightlights:

1) J-Link V8 use AT91SAM7S64, expanding the capacity of Flash and SRAM to facilitate future upgrades;

2) J-Link V8 improves the SWD interface, an increase of driver chips, (V6 and V7 in the SWD is a direct quote from the pin to the target CPU board);

3) J-Link V8 SWD improved control methods, V7 is the I / O direct-drive, V8 with a special method, there is not effective anyway V8`s SWD velocities slower than the V7

4) J-LinkV8 have three lights, one directed USB Communications, a direct target CPU, reset state, a direct 5V output is turned on V7 only 1 USB communication indicator

5) J-Link V8`s firmware update process is not DLL, and can not write the same as V7 Bootloader on a simple easy to crack V8`s Bootloader need to implement USB device connectivity;
