Difference between TM4C123GH6MPI & TM4C123fH6PMI

Other Parts Discussed in Thread: TM4C123GH6PM, TM4C123FH6PM

Hi,

My chip TM4C123GH6PM on the Tiva launchpad was damaged so replaced it with TM4C123FH6PM.

Now some I/O pins not work ( Ex:  C4,C6,C7 ,D0,D2,D3...). 

Are there any differences between TM4C123GH6MPI & TM4C123fH6PMI ?

    Hi,

    You, can see the difference at both product website's under Parametrics.

    Hi,

    Thank you, but it's not mention when you use it.  I change the variant to TM4C123Fh6PM then debug my code ( write for Tm4c123GH6PM)  to TM4C123FH6PM and it's not work 

    I use 4 pins:  A2,A3,A4,A5 to read Sd card ;  8 pins data:  D0-D3 and C4-C7 in my project.

    Do i have to config those pins in TM4C123FH6PM different ?

    regards,

    I checked both datasheets and these pins, have same pin outs for both TM4C123FH6PM and TM4C123GH6PM.

    If program a .bin file using LM Flash Programmer are there any errors?

    Maybe, you need to set this below at Preprocessor Symbols.

    PART_TM4C123FH6PM

    Hi,

    I don't know how to use LM Flash Programmer.

    I have changed the variant to TM4C123Fh6PM and predefine PART_TM4C123FH6PM

    Well, i think have to remove the mcu TM4C123FH6PM and replace with TM4C123G

    regards

    Have you described (beyond) "some pins NOT Work?"    Really - what does that mean?

    Earlier you state that the original MCU became damaged - you do not state, "How or Why" nor what you've done to prevent the "identical damage" to, "Next (MCU Victim!")   Might you have (similarly) killed MCU #2?    (again - we're not told)

    What's connected to those (failing) pins?   It is extremely unusual for MCU pins to "die of their own accord."   We (always) look at our "mis-treatment" and blame the device far, far later.  (i.e. Never!)

    Replacing components w/out analyzing and correcting the (likely) cause of failure - may not make great sense.   (nor insure the reasonable "lifetime" of the hapless replacement part...)

    Hello Khoa,

    Did you check if the cause of what damaged the TM4C123GH6PM has been first found and corrected. Could it be that the cause is affecting the replacement MCU as well?

    Make that (now) TWO votes for, "Find & Correct" the cause of the damage - prior to, "Next victim!"
