Building firmware for GW32 - need help

[androidonis]

Hello all, I started to built a firmware for GW32 watch. I am not experienced with workflow, but managed to get Espruino running on a MDBT42Q board. The GW32 is still stock firmware, but I have a j-link interface to mass erase and flash something on it. If someone has hex files, it would be great.

My starting point was this board file:

https://github.com/jeffmer/Espruino/blob/master/boards/GW32UNBUF.py

First I needed to add paths for libs:
'INCLUDE += -I$(ROOT)/libs/banglejs -I$(ROOT)/libs/misc',

After this I got an error for LCD_BL. I compared the board file with DICKENS as it has same graphics and added:

         'controller' : 'gc9a01', # was gc9a01a
        'pin_bl' : 'D24',  # was missing in source  

Further I added

'BAT' : {
'pin_charging' : 'D22',
'pin_voltage' : 'D31'
}

GW32UNBUF.py

This was enough to generate bootloader file, but the release compile runs into error: unknown type name 'nrf_uarte_baudrate_t'
I found that this problem is known and can be adressed changing usart from 0 to 1. (https://github.com/orgs/espruino/discussions/1142)

 'usart' : 1, #was 0 

Now I get errors in the LD step and warnings regarding spi_clk:

....

I hope that someone with better experience can help me out to get something running on the GW32.

Did that GW32 file not build in the repository it was in? Or you were trying to use it with the current firmware from https://github.com/espruino/Espruino?

I'm not sure why you'd be getting undefined reference to nrf_queue_read' - that's an odd one.

But one issue you have is you're building with 'DEFINES += -DBANGLEJS' but then not including jswrap_banglejs.c like https://github.com/jeffmer/Espruino/blob/master/boards/BANGLEJS2.py#L59-L60

jeffmer's ports were always trying to work without including jswrap_banglejs.c and implementing everything in JS - so you really have two options:

• remove 'DEFINES += -DBANGLEJS' and hopefully it'll behave more like a standard Espruino device and you can use jeffmer's JS code
• include jswrap_banglejs.c and try and modify it to work with GW32 - it'll likely need a few changes (esp for initialising the graphics) but if you can get that working it's more likely to be something that's a bit more compatible with Bangle.js apps

Yes I want to use the rather old board file with a new Espruino (cloned it end of August). My hope was to get something with nrf52840 and GC9A01 display, it is basically very similar to ID205 but with controller GC9A01 used in Dickens. I tried the ID205 built now, but this is not running with error:
In file included from targetlibs/nrf5x_15/modules/nrfx/nrfx.h:44,
from targetlibs/nrf5x_15/modules/nrfx/drivers/src/nrfx_gpiote.c:40:
targetlibs/nrf5x_15/integration/nrfx/nrfx_config.h:45:10: fatal error: sdk_config.h: No such file or directory
45 | #include <sdk_config.h>
| ^~~~~~~~~~~~~~
Not sure what in the board file ID205.py caused this.
Using my GW32UNBUF and a modified jswrap_banglejs.c is what i am currently working on....
I hoped that it is still ready to use the gc9a01 graphics.

[gfwilliams]

The errors from targetlibs/nrf5x_15 are a bit concerning. You didn't manually put that in rather than using provision.sh did you? Can you build the BANGLEJS2 board ok?

[androidonis]

As you expected same nrf error. Maybe I need an older version of this. Mine was installed a few days ago.

No idea why the reference is not found:

Runs through after removing in nrf_queue.c :-)
#if NRF_MODULE_ENABLED(NRF_QUEUE)
#endif // NRF_MODULE_ENABLED(NRF_QUEUE)

[androidonis]

adding -DNRF_QUEUE_ENABLED=1 in the board file cures the problem.
