Yes V5 got V5.0, 5.2, 5.3 and 5.4 as per Segger documentation. I got the following info from Segger documentation, the old doc documented up to 5.2. The new documentation does not mention V1 - v4, just saying that they are obsolete. Differences between different versions Versions 1-4 (obsolete) These J-Links use a 16 bit CISC CPU. Maximum download speed is app. 150 kB / sec. JTAG speed Maximum JTAG frequency is 8 MHz; possible JTAG speeds are: 8 MHz / n, where n is 1,2, ..., resutling in speeds of: 8.000 MHz (n = 1) 4.000 MHz (n = 2) 2.666 MHz (n = 3) 2.000 MHz (n = 4) 1.600 MHz (n = 5) 1.333 MHz (n = 6) 1.142 MHz (n = 7) 1.000 MHz (n = 8) Adaptive clocking is not supported. Version 5.0 Uses a 32 bit RISC CPU. Maximum download speed (using DCC) is over 650 kB / sec. JTAG speed. Maximum JTAG frequency is 12 MHz; possible JTAG speeds are: 48 MHz / n, where n is 4,5, ..., resutling in speeds of: 12.000 MHz (n = 4) 9.600 MHz (n = 5) 8.000 MHz (n = 6) 6.857 MHz (n = 7) 6.000 MHz (n = 8) 5.333 MHz (n = 9) 4.800 MHz (n = 10) Target Interface nTRST is push-pull type RESET is push-pull type Version 5.2 Uses a 32 bit RISC CPU. Maximum download speed (using DCC) is over 650 kB / sec. JTAG speed. Possible JTAG speeds are identical to these of version 5.0. Target Interface nTRST is push-pull type RESET is open drain Version 5.3 Identical to version 5.2 with the following exception: 5V target supply current limited 5V target supply (pin 19) of Kick-Start versions of J-Link is current monitored and limited. J-Link automatically switches off 5V supply in case of over-current to protect both J-Link and host computer. Peak current (<= 10 ms) limit is 1A, operating current limit is 300mA. Version 5.4 Identical to version 5.3 with the following exception: Supports 5V target interfaces. Version 6.0 Identical to version 5.4 with the following exception: Outputs can be tristated (Effectively disabling the JTAG interface) Supports SWD interface. SWD speed: Software implementation. 4 MHz maximum SWD speed. J-Link supports SWV (Speed limited to 500 kHz) Version 7.0 Identical to version 6.0 with the following exception: Uses an additional pin to the UART unit of the target hardware for SWV support (Speed limited to 6 MHz). Version 8.0 Identical to version 7.0 with the following exception: SWD support for non-3.3V targets. > I updated the V6 to the latest version and it still works fine. > J-Link ARM V6 compiled Feb 1 2011 14:28:14 > > tested with/without patches. -- Xiaofan ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
