Nrf51822QFAAC0 program stuck

[tsy19950218]

Nrf51822QFAAC0 uses softdevic: s110_nrf51822_6.0.0-5.beta, sdk: nrf51_sdk_v5_1_0_36092. Use serial routines. When I annotate the initialization of serial port, and annotate the serial port print function, the program will be stuck for a period of time, and then restart.

When I open NRF_UART0->ENABLE= (UART_ENABLE_ENABLE_Enabled << UART_ENABLE_ENABLE_Pos);
NRF_UART0-> TASKS_STARTTX = 1; not stuck

When I annotate advertising_start(); it won't get stuck.

When I close NRF_UART0->ENABLE= (UART_ENABLE_ENABLE_Enabled << UART_ENABLE_ENABLE_Pos);
NRF_UART0-> TASKS_STARTTX = 1;and no comment advertising_start();Programs that run for a while get stuck.

What is the reason for this?

Hi,

Nrf51822QFAAC0 uses softdevic: s110_nrf51822_6.0.0-5.beta, sdk: nrf51_sdk_v5_1_0_36092.

This is the very first production silicon of the nRF51822, and you are using a beta version of a very old softdevice as well.

It is recommended that you use the latest revision of the chip for development and production (revision 3) in combination with a newer SDK and softdevice.

 

Kind regards,

Håkon

I now have a shipment of chips in C0 version. I need to get rid of this. I want to deal with it through software. The cost of chip replacement is a little high. Do you have C0 version support?

It is highly recommended that you do new development and production runs with the latest chip revision.

Please see this document for which softdevice and SDK works with revision 1:
