there is no action in nrf52832DK after power or close SES

[zhengrui]

Hello,

 I am using nrf52832 and nrf5 SDK12.3 to develop my project.

When I debug it in SES and it works well,but when I stop debug or close SES or power off and power on again,the nrf52832DK doesn't work anymore neither BLE nor peripheral.

What's worse, I can't find any reason or solution about this problem.

So I need your help urgently.

Any help can be thanked very much.

Zhengrui.

Hi

Before diving into your code, I skimmed through some earlier cases here on DevZone to see if I could find someone having a similar issue. I found this case, which has a problem with resetting in debug mode, and solved it by writing to a register to explicitly restore the reset pin function. This issue is also in SDK v12, so I suspect there is a bug in that SDK somewhere.

Seeing as you are using an old SDK, I think the best way to solve this would be to migrate your project to a newer SDK (15.3 preferrably). Here are links to migration guides from 12 to 13, 13 to 14 and 14 to 15. Please check out the migration guide, as I believe that will solve more issues for you in the long run, rather than staying in SDK v.12.3.

Best regards,

Simon

Hi Simon

I've  updata the project into sdk15.0,but there 're some trouble to read registers.Everything I read is 0xff including WHO_AM_I.When I read WHO_AM_I register via spi (not spim) from the address of 0x0f,after the code :

spi_xfer(p_instance->p_reg, p_cb, p_xfer_desc);

I can read something but worong value.

the same code in sdk12.3 can work ,but it get into trouble in sdk15.0.I tried but can't find reason.

Hi

Due to the Easter holiday we are understaffed and you will have to expect delayed replies. Sorry for the inconvenience!

Can you check that your nrfx_spi and "regular" spi values in sdk_config.h are the same? There is a header file (apply_old_config.h) which might be causing trouble in migrated projects.

Best regards and happy Easter,

Simon
