Tool/software:
Hello Everyone,
I 'm trying to ouptut severals clock from the LMK04826B evaluation board. i have setup a configuration using TICSPRO software.
Following the programming sequence in section 9.5.1 from datasheet, i have some issues with some registers that seems to be "locked" and can't be written. here a log of my programming application.
The application is performing a write then a readback to check that the registers have been written.
starting LMK init sequence...
reseting lmk...
reset LMK OK

error :register 0x145 != 127
I'm not worried about the writing issues from 0x03 to 0x0D since they are product ID , vendor ID stuff there are probably in read only , and i plan to remove the programming of these in my app.
but for other registers like 0x107 , 0x108 and so on i don't have answers.
Could you please advice or give details on the programming sequence ? should i wait for something before writing some specifics registers ? if yes which registers should i check ?
( have tried waiting 10 ms between each write without succes)
Best regards,
Pierre
