    While "sympathetic to your plight" - none here "caused/contributed" to your sense of "urgency" - (yet "we" are being tasked to work "fast/furiously") - is that not true?

    By "Urgent" - do you seek "priority for your post" - over (all) others (even those arriving prior to yours)?

    Use of "Urgent" most always "sends a signal of "expectation" - "labels" one as a "seeker of special treatment!" (i.e. unwilling to "wait their proper turn.")

    Many - "helpers" noting "urgent" - will "Delay or Abandon their response" - due solely to the appearance of (the offensive) "urgent!"

    With this said (perhaps you can edit away the Subject Line "offender") you may employ the "Forum Search Capability" (found atop the forum page) using the keyword "FATfs long file name" in hope that (others) have resolved this issue. (my choice - was & remains - use of file names "escaping" such restrictions...)

    Hello Ye,

    I see, sorry I did not understand from your initial post what exactly you were saying (it seemed you couldn't find the makefile for the FatFS example in general).

    Looking through the example, I don't see any references that would indicate it is supposed to cover long file name - you said it's not enabled, is there any documentation or section of code which indicates that FatFS example includes long file name support? If so please direct me to that so I can look into it further.

    My suspicion at first look though is that the example does not support long file names and you would need to implement that yourself.

    As earlier stated/posted - as poster's situation is "critical" (as he arrived here late) should he not (simply) modify those "long file names" so that they ARE accepted?

    You will have to create a "listing document" which reveals the "shortened file name's content" - possibly even its "original, long file name." My firm has done "just this" - and as we DID note, "Long File Name" (which appears ONLY in the Subject Line - explaining vendor's "miss") our conversion of file names to "shorter, (i.e. acceptable format) led to success!

    Should it not be AGAIN NOTED - that even though vendor agent (tried) to claim the recent forum work as "Upgrade" - the long reported (by myself & others) "Failure to display the Subject Line - while the post is open" - caused this skilled vendor agent to MISS the key poster requirement!     (i.e. long file name!)

    Note: you must "shorten the file names" before compiling!     If (other/potential) users are "remote" from you - you must provide them w/the "listing document" (referenced above)...

    As time is tight - and vendor (even though "TI thinks resolved" - perhaps yet another forum miscue!) now agrees that you are stuck - my earlier suggestion appears, "Best/Brightest" - and your ONLY chance for "quick/eased SUCCESS!"    (you may (both) LIKE and verify this post - thank you...)    Vendor should Kill the "TI resolved claim."

    Hi

    I want to enable long file name feature for tiva c EK-TM4C1294XL board. I can enable long file name in msp432 by modifying and recompling fatfs files. but for now, tiva c series, I cannot find makefile to run gmake.exe. can someone know how to modify and run it to enable long file name features for fatfs in tiva series?

    Best regards

    Hello ye,

    Thanks for the background with how you got it working for MSP432.

    I had searched TM4C Forums for any cases of Long File Name being used but didn't come up with anything related to your issue but I checked the TI-RTOS forums as well and found the following thread which may be all you need as it seems to align with what you described you did for MSP432: e2e.ti.com/.../337537

    Again - "Never/Ever" is the "need for long file name" explained/justified. Yet - poster's case is (self-described) as "urgent."

    Can it be that, "Potential number of "files in play" demand such, "Long file names?" If not - the conversion from long to "acceptable length file names" seems an eased & speedy, "sure thing..."

    Rejecting "KISS" (even though banned here) may not always prove well founded...   (as is - "accepting poster's desire" w/out ANY poster-justification for such need!)
