Writing data - SECUREAPPROTECT disabled

Use the standard Serial Wire Debug (SWD) Arm® CoreSight™ Debug Access Port (DAP) protocol to write data into flash.

1. Set the CONFIG register of the NVMC to WEN.Wen by writing 0x00000001 to the following addresses:
   • Application core - 0x50039504
   • Network core - 41080504
   This enables writing to the non-volatile memory.
2. Read the READY register (0x50039400) of the NVMC until the value is 0x00000001. Read the following addresses:
   • Application core - 0x50039400
   • Network core - 0x41080400
   When this value is read, the NVMC is ready and not currently performing any operations.
3. Write the data to the desired, word-aligned address.
4. Read the READY register of the NVMC until the value is 0x00000001 before continuing to ensure the write operation has completed. Read the following addresses:
   • Application core - 0x50039400
   • Network core - 0x41080400
5. Continue writing and then reading the READY register as necessary.
6. Set the CONFIG register of the NVMC to WEN.Ren by writing 0x00000000 to the following addresses:
   • Application core - 0x50039504
   • Network core - 41080504
   This configures the non-volatile memory as read-only.
