02 How we work
From a board that boots to firmware you can own.
Every engagement runs the same four stages on the tool chain GSAS supplies, so the evidence your reviewers ask for is produced along the way. Hover a stage to find it on the line.

04 Working together
Three ways to start.
Hand GSAS the firmware, buy the tool chain your own team needs, or have your engineers trained on it. Many teams do all three.
-
01
A firmware project
Scoped to your board and deadline
Tell us the silicon, the operating system and the milestone. GSAS engineers bring up the board, integrate the stack and hand back verified firmware your team can build and own.
-
02
The tool chain
Arm, SEGGER, Perforce, Razorcat, Solid Sands
The compilers, probes, unit-test and static-analysis tools on this page are available from GSAS in India, with INR quotes, GST invoices and application engineers who use them on real projects.
-
03
Your team, trained
Workshops on your hardware
Hands-on sessions for your engineers on the tool chain, RTOS and debug workflow, run on your own boards so the lessons carry straight into the product.
05 Contact
New silicon on the bench? Let’s bring it up.
Tell us the processor, the operating system and the milestone. GSAS replies from Bengaluru with scope and a proposal: bring-up, integration, verification and the tool chain to keep it going.

Can GSAS migrate our firmware from IAR or GCC to Keil MDK?
Yes. GSAS translates keywords, pragmas and intrinsics, converts IAR .icf and GCC .ld linker files to Arm scatter-loading, migrates the C library, integrates the new build into CI and shows functional equivalence with a MISRA re-check.
Which RTOS and operating systems does GSAS integrate?
RTX5, SEGGER embOS, FreeRTOS, Zephyr and ThreadX for real-time work, and embedded Linux built with Yocto or Buildroot for Cortex-A targets.
Can we buy the tool chain from GSAS as well?
Yes. GSAS is the authorized Arm development tools engineering partner for India, the UAE and Sri Lanka. It is also an authorized SEGGER engineering partner in India, and it supplies Perforce, Razorcat and Solid Sands tools, with INR quotes and GST invoices.

Arm User-Based Licensing in CI/CD: armlm, Proxy Activation and What Breaks
A licensing failure in an Arm pipeline blocks the release branch and puts a firmware engineer on armlm output instead of driver code, up to seven days after the change that caused it. The reason: a UBL licence is a cached certificate valid for 7 days, not a checkout. Here is what that changes about pipeline design, and what to fix first.
