Hello!
I am having problems reading the SIPINFO on the SoC. I started with the TFM sample and added some lines to read the silicon version.
added lines:
printk("FICR->INFO.VARIANT: 0x%08x\n",
secure_read_word((intptr_t)&NRF_FICR_S->INFO.VARIANT));
printk("FICR->INFO.DEVICEID: 0x%08x\n",
secure_read_word((intptr_t)&NRF_FICR_S->INFO.DEVICEID));
uint32_t partno = secure_read_word(0x00FF0000UL + 0x140); /* SIPINFO.PARTNO */
printk("Partno: 0x%08x\n", partno);
And i get error when coming to the SIPINFO.
