Hello,
Our company has a j-link, and when I connect it via USB to the PC running jlink.exe I get:
S/N: -1
This is shutting me down, because when I try to program flash memory (with trial licenced J-Flash ARM) I get:
Could not read unit serial number!
The j-link details are:
serial number: 672 (black box)
version 3, marked with 'IAR systems' logo.
p.s. . I am developing with an ARM 7 core, and have been able to read memory, get device i.d, test speed with the SEGGER tools, but not program in spite of having a valid licence key for j-flash ARM. Have also emailed IAR for advice. I don't know the exact origin of this j-link unit. I also note that the
firmware was last updated October 2006.
I Would appreciate any advice.
