Process for porting lpcxpresso54018 SDK examples to an LPC54018JBD208 package

[mitchkapa]

We are working on a project where we have been doing our development on LPCXpresso54018 eval board.  Yesterday we got in our custom PCBs which use the LPCXpresso54018 as a reference design (same external flash, same SDRAM, same LCD) however our custom PCB uses the *208 package.  I attempted to run some of the basic SDK example programs (hello_world, gpio_led_output) on our custom PCB after changing Project Settings>MCU>package to match our part but so far have failed to get any of those to run.  I can only successfully run code on our custom PCB if I use create a New Project and have the *208 selected from the start.

Are there step by step directions available for how to successfully modify an SDK example program so that it can run on the LPC54018JBD208?  Thanks.

HI

MCUXpresso IDE user guide documents how to change MCU package type.

then go to pin config, make sure pin mux configuration correct for the new package.

I suggest you testing it with a simple led blinky demo code first, to make sure the procedure correct. If still fails, we need to connect and debug code to position where is the problem.

Thanks,

I once again tried to start from a simple SDK example (drivers->gpio_led_output) and then make all of the necessary changes (package, pin configuration) to match our processor.  I am still having the same result of not being able to successfully run the code on the processor.  Here is an example message that I get after running Debug:

"Break at address "0x300084c" with no debug information available, or outside of program code."

I feel like there must be one other location where a change needs to be made that is missing.

Also of note is that even after changing the package through the IDE the old package still appears within the Preprocessor Defined Symbols:

CPU_LPC54018JBD208
CPU_LPC54018JBD208_cm4
__REDLIB__
CPU_LPC54018JET180=1
XIP_IMAGE
MXL12835F
CPU_LPC54018
__USE_CMSIS
W25Q128JVFM
SERIAL_PORT_TYPE_UART=1
SDK_DEBUGCONSOLE=1
CR_INTEGER_PRINTF
PRINTF_FLOAT_ENABLE=0
__MCUXPRESSO
DEBUG

I am not sure if this is an error or is intentional.  I have tried removing that entry but it does not impact the results.

Hi

You met error when launch debug window or during debug?

Please send all the error message displayed in console window. I will check.

Thanks,

I get the error after launching Debug.  It goes through the initial process but then there is never an option to Resume or Step through any code.  Below I will show a screenshot of what appears in the IDE after pressing Debug and also I will paste the Console Debug messages.

We have an update to this problem.  It appears to specifically be a problem with the SDK_2.xLPCXpresso54018 (installed version 2.8.2).  If I select examples from SDK_2.x_LPCXpresso54S018 (installed version 2.11.1) I can successfully import SDK examples and change the processor package and run those examples on our custom hardware.  For our project this is an acceptable solution.

[ZhangJennie]

So the problem was on old SDK package. New version fix the issue. Thanks for the sharing.

[mitchkapa]

Is the "non-S" SDK considered to be an older package than the S version?  I have been viewing both SDKs as separate and valid.  If that is not the case I think there should be some messaging or documentation to help make sure that people end up with the "S" version of the SDK.  Otherwise I think people like myself who purchase the LPCXpresso54018 development board end up with the "non-S" SDK by default.

[ZhangJennie]

Do you mean SDK for LPC54018 and LPC54S018?

These are two parts, not related with old or new.

S version has security feature while non-S doesn't. besides this feature, others are the same.LPC54018 can run on LPC54S018 without issue. 

See below:

Thanks,

Yes that is my point although we personally do not need a corrective action for our project (because we can use the LPC54S018 SDK) I believe NXP may want to investigate and confirm if the LPC54018 SDK has some bug that prevents changing the MCU package.

[ZhangJennie]

Hi mitchkapa 

LPC54018 SDK hasn't been updated since SDK2.8.2

I will report it.

Thanks for bringing this problem to our attention.
