  • [SOLVED] Breaking changes updating from JLINK SDK v4.56 to v.502

    I'm responsible for a software that uses the JLINK ARM Flasher to program STM32 processors, six at a time.

    Now we've purchased JLINK SDK v5.02, mainly to support a new version of the STM32 processor, and I encounter problems when I try to update our software.

    I installed the SDK on our development computer and copied the following files from C:\Program Files (x86)\SEGGER\JLink_SDK_V502d, overwriting the old versions:

    JLINK.h, JLINKArm.dll, JLINKARM_Const.h, JLINKARMDLL.h, TYPES.h and Version.h

    The problem is that all the methods under the Flash Programming API section in the old JLINKARMDLL.h file has gone missing. I get errors saying that the following methods are unknown:

    JLINKARM_FLASH_ ...CloseDataFile, ...Program, ...EraseChip, ...VerifyCRC, ...Verify, ...AddBank, ...SetClockSpeed, ...SetBankPara, ...OpenDataFile


    I can't seem to find any similar methods in the new SDK. Have this functionality been moved to another DLL OR SDK?

  • Hi Bolddp,


    unfortunately, Flash API was removed in Jan 2013 with V4.62 of J-Link SDK.
    All features which were provided by the Flash API are available in the General API.

    The General API functions are described in UM8002 chapter 4 "General API", section 4.3 "API functions".
    An upgrade is strongly recommend, since V5.02 does not only introduce support for new devices, but also provides significant performance improvements (especially with Cortex-M cores).

  • Hi, Niclas, and thx for the prompt reply!
    Yes, we will need to upgrade since a new processor model with larger memory has been introduced.

    I'll have a look at the documents and post any problems I encounter during the refactoring here.

    Best regards
