Hi Mr_sev,

Could you try to remove comment out the 2 lines in bootloader_info_on_flash_idle() in bootloader_info.c as follow and let me know the result:

void bootloader_info_on_flash_idle(void)
{
    m_write_in_progress = false;

   // mp_info_entry_head = (info_buffer_t*) mp_info_entry_buffer;
   // mp_info_entry_tail = (info_buffer_t*) mp_info_entry_buffer;
