Install SDK multiple options for same microcontroller

[bwinter]

I have a question about adding a SDK to the MCUXpresso IDE.

When is select a microcontroller in the "Install MCUXpresso SDKs" i get multiple choices with different names but the same supported microcontrollers.

for example when i select: LPC845 i get 2 options.
Device: LPC845
SDK: SDK_2.x_LPC844 and SDK_2.x_LPC845
Both support the exact same four packages: LPC845M301xx  

For other microcontrollers i get up to 4 options

a) which SDK option is the best. (if both are the same why name them differently)

I will start with the LPC845 breakout board because it's easy testing but will move to a LPC824 down the road (and use my own hardware).

b) can i easy change a SDK inside an existing project?

If you use LPC845 breakout board board, download this package as attached screenshot.

Here is an article of How to Create Custom Board MCUXpresso SDK

Dear Jun Zhang,

thank you for your answer however i still don't know which SDK i should select.

In the screeshot you see 1 choices if i select the LPC845 ANd even 4 choices when i select a LPC55S28 microcontroller (other project)
Is there dfference? In the document of your link the LPC845 choice points to a xxx844 device name?

Hi bwinter.

I don't know why attachment is missing in my last post. 

I attach it here for your reference

Please go to 

https://mcuxpresso.nxp.com/en/select

and download SDK_2.8.0_LPC845BREAKOUT for your board.

Have a nice day,
