s132 softdevice + example code not working

[Stigui]

Hi, I’m having some troubles with example code : ble_app_uart_s132_pca10040. The code compile well in Keil and I can prog it in the nfr52 but it doesn’t run. When I check the code step by step in debug session, I enter in ble_stack_init() function, but resart entering in the function SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL) (error_code = 0x10). I can’t figure out where is the problem. I work with with softdevice s132_nrf52_4.0.2 and SDK 13.0.0 (I tried with s132 4.0.3 but the result is the same). For information, I have replaced the files presents in SDK\components\sorftdevice\s132\headers by those presents in include folder of the API and… it doesn’t change anything. In Keil configurations I start the IROM1 at 0x1f00 with 0x61000 size and the IRAM1 starts at 0x20001f00 with a size : 0x6100. Do you have any solution to my problem please? Thank’s.

I see that you have nrf52840 in the tag, if that is the case you need use the S140 Softdevice, and the project named ble_app_uart_pca10056_s140

My mistake. I’m using nrf52832, sorry for that, I change the tag right now!

Ok, the IRAM looks wrong. It should be start: 0x200025f8 with size: 0xda08. If this doesen't fix the issue, download a new copy of SDK 13 from here.

Thank you for your answers, I changed de IRAM and it’s still not working, as you suggest I’ll try to download a new copy of the SDK. Where did you find information about the use of RAM with s132? (I can find easily information about ROM but that's harder for RAM). Thank’s

The value I listed is the default value for the example. The RAM usage will increase if you add more services, characteristics, etc. If you enable logging, the RAM size required should be printed on the terminal. E.g. :

**SDH:INFO:sd_ble_enable: RAM START at 0x20002168
SDH:WARNING:sd_ble_enable: app_ram_base should be adjusted to 0x20002128
SDH:WARNING:ram size should be adjusted to 0xded8**

Make sure that you have #define NRF_LOG_BACKEND_SERIAL_USES_UART 1 and #define NRF_LOG_ENABLED 1 in sdk_config.h if you are printing over UART.
