LMK03328: EEPROM programming

Expert 6370 points
Part Number: LMK03328
Other Parts Discussed in Thread: CODELOADER,

Dear Team,

our customer has a question on programming EEPROM of LMK03328RHST - could you help finding the answer?

In the datasheet chapter 10.5.5 Write EEPROM, it is written:

We implemented EEPROM programming according to chapter 10.5.5 Write EEPROM but R136 did not increase (NVMCNT register in EEPROM increased). Register R136 is increased after power-on sequence.

a) Can we test NVMCNT register in EEPROM instead of R136?

b) Do you have any software that could build configuration files in other than *.epr format?

Thanks for your help,
Bartosz

  • Hi Bartosz,

    Q1) Can we test NVMCNT register in EEPROM instead of R136?
    A1) Yes, you can read NVMCNT in EEPROM instead of R136.
    From datasheet section 10.60109: "The NVMCNT value is retreived automatically after reset, after a EEPROM Commit operation or after a Erase/Program cycle". This explains why R136 is updated after the power cycle.

    Q2) Do you have any software that could build configuration files in other than *.epr format?
    A2) You can use the CodeLoader software with the LMK03328EVM to generate a config file. If you do not want a file in the *.epr format, you can export the register values in hexadecimal to a text file to directly program the device registers.

    Kind regards,
    Lane
  • Hi Lane, Hi Bartosz,

    I'm Bartosz' customer. Thank you very much for your effort.

    May I ask you if we can have description of *.epr format to be able implement processing of files in this format in our programming tools?

    Best regards,

    Frantisek

  • Hi Frantisek,

    LMK03328EVM CodeLoader Software User's Guide has a description of the *.epr file format. See Figure 11: www.ti.com/.../snau185.pdf
    Table 10.7 of the datasheet gives the EEPROM Map that corresponds with a LMK03328 EEPROM file. www.ti.com/.../lmk03328.pdf

    Kind regards,

  • Hi Lane,

    Thank you very mush, this is exact what we need.

    Best regards,
