8.1 Firmware update
The TM NPU firmware consists of two parts:
• NPU processing unit (Myriad X): LZ4 file
• Backplane bus interface (PER ASIC): UPD file(s)
To update the firmware of the TM NPU, the following steps must be followed:
1. Create the folder "FWUPD" on the root directory of the SIMATIC Memory Card
2. Place the LZ4 file in this folder
3. Inserting the SIMATIC Memory Card in the TM NPU
4. Ensure presence of the 24 V DC power supply on the module
5. Perform the TM NPU firmware update via the SIMATIC S7 Standard Firmware Update
mechanisms (e.g. in the TIA Portal) using the UPD file(s).
NOTE
Important: The LZ4 file must not be modified or renamed when it is copied to the
SIMATIC Memory Card.
The firmware update of the TM NPU is initiated by triggering the update via the SIMATIC
firmware update mechanisms. The module uses the file name to locate the LZ4 file which
matches the UPD file version on the SIMATIC Memory Card, and then updates both
components (the processor unit and the backplane bus interface) accordingly. If the
matching LZ4 file cannot be found on the SIMATIC Memory Card in the "FWUPD" folder, the
update will be aborted.
A firmware update of the TM NPU is only possible when the CPU is stopped.
