Kool Koala: what the DMSC firmware banner codename means
DMSC Firmware Version 9.1.8--v09.01.08 (Kool Koala)Kool Koala is the internal TI codename for the TI System Firmware 9.x release stream: the DMSC (Device Management and Security Controller) firmware that runs on the security-enclave core of every K3-family SoC (AM62, AM62A, AM62P, AM64, AM65, J7-series, etc.).
The full banner DMSC Firmware Version 9.1.8--v09.01.08 (Kool Koala) decodes as:
- 9.1.8: semantic version within the 9.x stream.
- v09.01.08: the same version in TI's alternate zero-padded notation.
- Kool Koala: the 9.x release-stream codename.
DMSC firmware is on its own release cadence, independent of Linux, U-Boot, and TF-A. Vendors ship it as a signed blob loaded from boot media at DMSC's first startup, then it stays resident for the life of the running system, servicing TI-SCI messages from every other core.
On AM62A specifically, "DMSC firmware" is a slightly misleading name because the role is split across two cores: TIFS (TI Foundational Security) runs on the Cortex-M4F security enclave, and the Device Manager runs on a companion Cortex-R5F in the wake-up domain. The banner covers both.
