Hello, I´m having a problem with the modification of the linker script to reserve the USB Endpoint RAM.
I´m following the instructions from the NXP application note AN10904, but i can´t compile the code.
I copied the files from the example inside a folder called "ld" situated in the root of the workspace directory (just as in the example).
Then, i put in the Project Properties->MCU Linker -> Target ->Linker Script = "../ld/usb_bufer.ld"

After I try to buil the code,i get this error: "cannot open linker script file ../ld/usb_bufer.ld: No such file or directory"

I´ve tried to put the linker files in another folder, but i get the same error.

Can anybody tell me what am I doing wrong?

Best regards,
Fernando

This error message is clear: your file can't be found :)

So either it's in a wrong folder or it's an ugly typo somewhere.

AN10904 describes a file called 'usb_buffer.ld', you are writing 'usb_bufer.ld' :confused:

Is this a typo?

In fact, if you are using LPCXPresso 3.6.x (or 3.8.x for Linux), then you should be able to accomplish the reserving of RAM for the USB ROM driver without modifying the linker script at all. Simply declare a new variable:

#include <cr_section_macros.h> 
__BSS(RESERVED) char USB_driver_memory[0x180] ;

Thanks for the answer.

Zero, it was a mistake. I wrote it wrong here, but I wrote it fine in the IDE.
