You need to use the s110 version of the LD

RE: Newbie having trouble getting started...

Got it Working! Several things had to happen. Used custom_board.h and SDK 6 was key. Thanks Cocoa for your help!!

One question: When I move to an example that requires Soft Device 110, will I still use gcc_nrf51_blank_xaaa.ld?

OK, I'm getting close. Do you know why these last errors are occurring in the blinky project?:

What is the current directory? Do the relative path for source files actually reach the files ? Does it creates _build folder? When you got fed up with makefile, go here and try Eclipse projects instead. I stopped using makefile long long long ago, since they days of Borland C++ with OWL 1.0.

Here is makefile.common:...it seems to be failing here but the error message doesn't tell me where it broke. Can you tell what the problem is? I'm unfortunatley not a makefile expert, but once I get this example running I will be out of your hair..:-)

The file structures are different from SDK7 to SDK8. You need to base on the makefile of SDK7. There are many differences in both source path and include path.

RE: Newbie having trouble getting started...

eq — Sun, 24 May 2015 04:27:28 GMT

Yes I have downloaded SDK 7.0 and SDK 7.2 and am trying to use them now instead of 8. Unfortunately I am getting the following error now when I try to make -f makefile on blinky:

Compiling file: system_nrf51.c
The system cannot find the path specified
make: *** [_build/system_nrf51.o] Error 1

Not sure how to get past this one as I'm not sure whats causing it. The same makefile works fine in SDK 8 and the file structures/hierarchy seem identicle.

RE: Newbie having trouble getting started...

RK — Sun, 24 May 2015 03:57:45 GMT

can you please format that with 4 spaces at the start of each line so it doesn't look so awful?

You're doing this with the blank version - no softdevice? Use nrfjprog to reset the board, make sure the code is on it. Until you can get this to work, you're not going to get too far.

RE: Newbie having trouble getting started...

Nguyen Hoan Hoang — Sun, 24 May 2015 02:59:12 GMT

I suggest that you check the chip revision as well. Chip rev 1 may not work with SDK8.

Hi RK,

I actually have the custom_board.h file for the board which was provided by Rigado. I have it configured in the Makefile with this line:

CFLAGS  = -DBOARD_CUSTOM

Here are the contents of custom_board.h:

#ifndef __BMD200_H__
#define __BMD200_H__

#define LEDS_NUMBER    3

#define LED_RED        1

#define BSP_LED_2      LED_BLUE

#define BSP_LED_0_MASK (1<<BSP_LED_0)

#define BSP_LED_2_MASK (1<<BSP_LED_2)

#define LEDS_MASK      (BSP_LED_0_MASK | BSP_LED_1_MASK | BSP_LED_2_MASK)
/* all LEDs are lit when GPIO is high */
#define LEDS_INV_MASK  0

#define BUTTONS_NUMBER 2

#define BUTTON_1       0
#define BUTTON_2       11

#define SPIM0_MOSI_PIN      1     /**< SPI Master Out Slave In GPIO pin number. */
#define SPIM0_MISO_PIN      2     /**< SPI Master In Slave Out GPIO pin number. */
#define SPIM0_SS_PIN        0     /**< SPI Slave Select GPIO pin number. */

#endif // __BMD200_H__

I have confirmed that it is linking this by defining BOARD_CUSTOM in the Makefile, removing custom_board.h from the directory and seeing it complain.

I have confirmed that the chip is: nrf51822_xxaa

Yes I would love to see an LED blink...so far no luck...

RE: Newbie having trouble getting started...

RK — Sun, 24 May 2015 02:19:55 GMT

I suggest going back to the start, with an untouched copy of the blinky sample code.

in the directory copy the pca100028 directory entirely to something, call it 'custom' or 'bmd200' or similar.
start with the 'blank' example not the s110 one, get a simple blinky to work first.
change all the -DBOARD=PCA100028 to -DBOARD=
write a board definition for your board which has the correct GPIOs for the LEDs and the BUTTONS, it's very unlikely that board has them mapped to the same pins. Put that in examples/bsp/ and edit the boards.h file to recognize your -DBOARD=.. or call it CUSTOM_BOARD and write custom_board.h, I personally like to have the actual board name in the file but it doesn't matter.

make clean and make it then upload it. When you can get that to blink the LEDs on your board, then try the s110 version which is the exact same code put at 0x18000 instead of 0x00000.

you can use nrfstudio or nrfgo to get it on the board, or use the JLink commands yourself if you want.

At some point you'll need to work out which chip you have and pick the correct .ld script but for these simple, tiny, short examples it doesn't make a jot of difference, all the code is in the early part of flash, all the RAM is in the early part of RAM (yes including the stack) so at this point they are all going to work.

Important points - get the LED and BUTTON mappings right for YOUR board, start with the simple blank example with no softdevice and get that going first.

.. and what does nrfstudio tell you about the revision of the chip you have, that will eventually be important
