J-Link offers highest debug and download performance into RAM and flash memory on all supported targets, a feature which is retained when debugging 8051 devices.
“We are excited to bring the proven reliability and outstanding performance of the J-Link line of debug probes to the 8051 development community. It shows that Segger can not only support 32-bit architectures like ARM, MIPS and RX cores, but also 8-bit architectures and still deliver the same benefits such as ease of use, high performance and direct download to flash memory,” says Alexander Gruener, Product Manager of the SEGGER J-Link family of debug probes.
J-Link is tool chain independent and works with free GDB-based tool chains such as emIDE and Eclipse, as well as commercial IDEs from: Atmel, Atollic, Coocox, Cosmic, Freescale, IAR, KEIL, Mentor Graphics, Microchip, Python, Rowley, Renesas, Tasking and others. With the J-Link family, investments in the debug probe are preserved when changing compiler or even CPU architecture.
J-Link supports multiple CPU families, such as ARM 7, 9, 11, Cortex-M, Cortex-R, Cortex-A as well as Microchip PIC32, and Renesas RX100, RX200, RX600, and 8051; there is no need to buy a new J-Link or new license when switching to a different yet supported CPU family or tool-chain.
