BL600 NUS service and DFU support

[sowmya]

Hello,

I am using BL600A module and Nordic softdevice and SDK9.0. The system is having NUS service and TX and RX characteristic. Now I have a requirement for firmware upgrade OTA.

My question is, Can I use DFU and bootloader without affecting the NUS service and its characteristics to upgrade the firmware?

How it can be done?

Regards,
Sowmya

No, it is not coming to main. Arguments for the external tool is --family NRF51 --program "#H" and the address is as below:

Update: This is a screenshot after debugging. Hex file is : nrf51422_xxac.hex Axf file: nrf51422_xxac.axf

This is the hex and axf file after changing the RAM registers: nrf51422_xxac.hex nrf51422_xxac.axf

This is the screenshot taken after executing and stopping:

Hi Vidar, if I just flash the program using F8 in Keil, I am getting the error : Reading flash area to program to guarantee it is erased. Checking that the area to write is not protected. Programing device.. Then I tried to debug the code, breakpoint is hitting main and when I execute, hardfault is occuring for CRC16 in the following code snippet:

uint32_t dfu_ble_peer_data_get(dfu_ble_peer_data_t * p_peer_data)
{
uint16_t crc;

if (p_peer_data == NULL)
{
    return NRF_ERROR_NULL;
}

crc = crc16_compute((uint8_t *)&m_peer_data, sizeof(m_peer_data), NULL);
if (crc != m_peer_data_crc)
{
    return NRF_ERROR_INVALID_DATA;
}
