General

The One Time Programmable memory is programmed sometime during the factory process and can never be changed afterwards. The Wii U's OTP is much larger than the Wii's (1KB split across 8 banks of 128 bytes each) and contains an assortment of read-only data, including the console's encryption/decryption keys.

Register List

OTP
Address Bits Name Description
0x0d8001ec 32 HW_EFUSEADDR OTP command
0x0d8001f0 32 HW_EFUSEDATA OTP data

Access U R/W U R/W
Field BANK ADDR
Field Description
RD Set to one to execute a read command. If clear, then the data in HW_EFUSEDATA is unchanged.
BANK Bank's number (0x0 to 0x7).
ADDR Word address to read, 0x00 to 0x1F (32 4byte words).

This register contains the command sent to the OTP. It is unknown whether is register is also used during the factory process to program the OTP.

HW_EFUSEDATA (0x0d8001f0)
  310
Access R

This register contains the output data for the last issued OTP read command. The execution of a read operation via the HW_EFUSEADDR register immediately changes this register without any delay.

IOSU

The Wii U's IOSU interacts with the OTP by setting it's respective Latte registers. In addition to this, the IOS-CRYPTO process is also able to access the OTP indirectly through syscall 0x22, which takes the OTP word index, a buffer to store the result and the requested size as parameters. The IOS-KERNEL then converts the word index: 

int read_otp_internal(int index, void* out_buf, u32 size)
{
  int i_res = disable_interrupts();
  
  if (size != 0)
  {
    int step = 0;
    
    while (step < size)
    {
      int word_addr = index + (step >> 2);
      int word_offset = word_addr & 0x1F;      // Each OTP bank has 0x20 * 4 = 0x80 bytes. Valid word indexes go from 0x00 to 0x1F.
      word_addr = word_addr << 3;
      word_offset = word_offset | 0x80000000;  // Set OTP read flag.
      word_addr = word_addr & 0x700;           // OTP bank goes from 0x000 to 0x700.
      word_addr = word_addr | word_offset;
      
      *(u32*)0x0D8001EC = word_addr;                     // Write to HW_EFUSEADDR
       u32 temp = *(u32*)0x0D8001EC;                     // Read from HW_EFUSEADDR
      
      *(u32*)(out_buf + step) = *(u32*)0x0D8001F0;       // Copy from HW_EFUSEDATA
      
      step += 4;	
    }
  }
  
  enable_interrupts(i_res);
  return 0;
}

syscall_0x22(index, out_buf, size)
{
  // Do some permission checks.
  ...
  
  // Internal IOS-KERNEL function.
  read_otp_internal(index, out_buf, size);
}

Production: 0x90000000
Development: 0x88000000
Factory: 0x00000000

Flag 0x40000000 causes an error in boot0.
Flag 0x80000000 means the console type has been programmed.
Flag 0x00000000 tells boot0 to not crypt or verify ancast images, skip OTP locking, and not require valid SEEPROM info (factory mode).
Flag 0x08000000 tells boot0 to use its first RSA key and development ancast images (development mode).
Flag 0x10000000 tells boot0 to use its second RSA key and production ancast images (production mode).
If both production and development flags are set, boot0 will throw an error.
