LMFlash and UniFLash Really need EEPROM tools

Other Parts Discussed in Thread: UNIFLASH, LMFLASHPROGRAMMER, SEGGER

Guys:

I saw the thread that described various methods of downloading code or starting your image to program EEPROM. This is the first MCU product line I have seen that did not have a tool to program *all* writable media inside the IC.

Our situation is the same as the original poster in that thread:: our production line needs to program a unified Flash image (boot loader plus original application) *and* the EEPROM where configuration data is stored.

A lot of us would really appreciate your efforts to find a way to do the EEPROM programming from the JTAG running on a PC.


Thanks.

Ray

    Believe you raise a valid point - thanks for that.

    Might you "raise the odds" of this vendor's (initial) study and (later) compliance by "listing" the "top" two or three (others) which may serve as a "model" (and incentive) for this vendor?     

    Anything which speeds/eases this vendor's efforts should prove to your, our (and this vendor's) advantage...

    Hello Raymond,

    EEPROM was initially designed for Application Data Storage and was never meant to be pre loaded. But yes, I see the point of what-if there is a requirement. This while not supported on the LMFlashProgrammer nor UNIFLASH in a direct method, we have worked out a gel file that can be used to do the same. The same method may be done in dss script of UNIFLASH.

    Rather a long running post.

    And - unfortunately - a not, "too well marked/road-mapped" post - many would say.      (to include o.p. - who appears unaware of this particular, "nook/cranny!")

    It appears Segger might support it through RAMCodes, it might be worth contacting them to see if they have existing support already.

    That's a good lead Robert - thanks.    Certain Segger tools do seem to require J-Link (fine for you/me) limiting perhaps for others, here...

    I was looking to see if we could consolidate some of our JTAGs for other products to the J-Link.

    Yep, J-Link would be necessary but if there really is a significant production issue that's not much of a tooling cost.

    I don't know how many other vendors of ARM JTAGs still exist but there may be others out there with possible solutions as well.
