LMK03328: EEPROM programming

Bart

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,
    Lane
