    JTAG download speeds using JLink

    amimjf

      Hi,

       

      I have a problem when i download using eclipse & gdb, the problem does not occur using Seggers tools like Ozone. Basically even though the download speed is set to 10000Khz, something sets it to 1000Khz. Log file captured from JLinkGDBServerCL.exe attached.

      I dont have a gdbinit file, so i was wondering where the "monitor speed 1000" and "monitor speed auto" was coming from ?
