fsl_power.c for LPC844 vs 845

HeMyFAE — Tue, 14 Apr 2020 23:32:42 GMT

DEar LPC 804 SDK team,

It seems that two FSL_POWER.c from 844 SDK vs 845 SDK are different.

844's fsl_power.c is much smaller and missing quite a few low power options compare to 845's.

Please advise!

Hi ,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Before answering your question, I'd like to confirm something with you.
1) Is it LPC804 or LPC844?
2) Which revision of SDK library does the fsl_power.c come from?

Have a great day,
TIC

Sorry I got my title mixed up.

It should be LPC844 and LPC845. The SDK are the latest 2.7.

Hi ,

Thanks for your reply.
After building an SDK library for the LPC844, I find this fsl_power.c is as same as the fsl_power.c that comes from the LPC845's SDK library.
I've attached the SDK library, please check it.

Have a great day,

HI Jeremy,

I don't see what you're talking about.

I unzipped your zip package below.

if you can see, in the 844 directory, the fsl_power.c file is only 2k and in the 845 directory, the fsl_power.c file is 5k.

There is a big difference in the two files if you exam it closely.

Regards,

Hi ,

Thanks for your reply, and I see it now.
I'll report this situation in the next round of field trials of the SDK library.

Have a great day,
TIC
