Manu ("Manufacturing") services are provided by the 010000000000B14A sysmodule, which is installed at the factory but not on normal retail systems.

manu

This is "nn::manu::IManu".

Cmd Name
0 InitUsbTransferPipeFsFile
1 FsFile_Exists
2 FsFile_Read
3 FsFile_Write
4 InitUsbTransferPipeRaw
5 Raw_Read
6 Raw_Write
7 [7.0.0+]
8 [7.0.0+]

All commands are wrappers for usb:ds requests with USB configured as:

VID:           0x057E (Nintendo Co., Ltd)
PID:           0x3000
bcdDevice:     0x0100 (1.00)
Manufacturer:  "Nintendo"
Product:       "NintendoSdkDebugger"
SerialNumber:  "SerialNumber"

SystemInitializer only uses cmd1..cmd3.

InitUsbTransferPipeFsFile

Takes an unknown u32 (ID?) and configures a transfer pipe over usb:ds for file access mode.

FsFile_Exists

Takes an input path string (type-0x9 buffer), returns 8-bytes for the output u8 flag.

Checks whether the specified file exists.

This is "FsFile::Exists" in SystemInitializer.

FsFile_Read

Takes a type-0x6 output buffer and a type-0x9 input string path buffer, and 3 u64s: <same size value from databuf>, unk, <same size value from databuf>. Where unk is probably offset?

Reads data from the specified file.

FsFile_Write

Same as FsFile_Read except the databuf is a type-0x5 input buffer.

Writes data to the specified file.

SystemInitializer also uses this as "FsFile::Create" with all input u64s set to 0.

InitUsbTransferPipeRaw

Takes an unknown u32 (ID?) and configures a transfer pipe over usb:ds for raw access mode.

Raw_Read

Takes a type-0x6 output buffer and 2 u64s: offset and size.

Reads raw data from the device.

Raw_Write

Takes a type-0x5 input buffer and 2 u64s: offset and size.

Writes raw data to the device.
