Firmware Engineering From Board Bring-Up to Connected Devices

Develop firmware that makes your hardware reliable, responsive, diagnosable, and connected. MayilVeera supports bare-metal systems, RTOS applications, embedded Linux, BSPs, device drivers, industrial protocols, and device-management functions.

Firmware Built Around the Real Hardware

Embedded firmware operates where software meets electronics. It must initialize the hardware correctly, handle timing and interrupts, communicate with peripherals, manage faults, and preserve predictable behaviour under real operating conditions.

MayilVeera develops firmware for new embedded products and supports existing systems requiring new interfaces, processor migration, protocol integration, performance improvement, or defect investigation.

Our Firmware Engineering Services

We work from the actual board, component documentation, interface contract, and expected system behaviour. Firmware assumptions are verified against electrical signals and target hardware.

Bare-Metal Firmware

For compact or tightly controlled applications, we develop firmware for system initialization, GPIO, timers, interrupts, ADC, DAC, PWM, serial communication, sensors, actuators, state machines, watchdogs, non-volatile configuration, errors, and diagnostics.

RTOS-Based Firmware

Where multiple time-sensitive functions operate together, we support RTOS selection, task and priority design, inter-task communication, timers, events, resource locking, memory and stack planning, watchdog integration, driver integration, timing, concurrency, fault handling, and recovery behaviour.

Embedded Linux Engineering

We support Linux platform configuration, Yocto Project customization, BSP integration, bootloader setup, kernel configuration, device-tree work, driver development and porting, root-filesystem customization, startup services, package integration, deployment, logging, diagnostics, image updates, boot-time tuning, and resource optimization.

BSPs and Device Drivers

We develop or adapt low-level software for GPIO, UART, SPI, I2C, CAN, Ethernet, USB, ADC, DAC, timers, PWM, displays, storage devices, sensors, and custom FPGA or peripheral interfaces.

Bootloader and Firmware Update Support

Depending on processor capabilities and product requirements, work can include boot sequencing, image validation, local update, recovery mode, version management, rollback considerations, secure-update design, and remote or over-the-air update integration.

Industrial Communication Integration

MayilVeera supports controller-neutral protocol work including OPC UA, Modbus RTU, Modbus TCP, EtherCAT integration and porting, serial communication, CAN, Ethernet application protocols, MQTT, device-to-gateway communication, and gateway-to-cloud communication.

Connected-Device Firmware

Connected firmware can include device identity, network provisioning, local configuration, telemetry, command processing, connection health, buffering, retry and reconnection logic, time synchronization, remote diagnostics, configuration updates, and firmware-version reporting.

Firmware Migration and Re-Engineering

We support MCU or MPU migration, RTOS migration, legacy-code refactoring, peripheral-driver replacement, compiler and toolchain upgrades, protocol-stack integration, 32-bit or 64-bit transitions, embedded Linux updates, feature additions, defect investigation, and stabilization.

Our Firmware Development Process

A structured firmware engineering process covering hardware bring-up, peripheral integration, communication, testing, debugging, and production readiness.

Understand

Review the hardware, interfaces, timing requirements, data flows, expected states, and failure behaviour.

Architect

Define firmware modules, execution model, memory use, interfaces, configuration, diagnostics, and update strategy.

Develop

Implement and statically verify modules using the agreed coding environment and version-control process.

Integrate

Bring up the software incrementally on the target hardware, verifying each peripheral and communication boundary.

Test

Exercise normal operation, error paths, timing, interface limits, restart behaviour, and recovery cases.

Document

Provide agreed source files, build instructions, configuration information, interface documentation, and test evidence.

Frequently Asked Questions

Q

Can you develop firmware without changing our hardware?

A

Yes, where the existing hardware can support the requirement. We first review processor resources, interfaces, documentation, and any existing source code.

Q

Do you support both microcontrollers and embedded Linux processors?

A

Yes. The appropriate approach depends on system complexity, real-time requirements, memory, user-interface needs, connectivity, boot time, and maintenance expectations.

Q

Can you port an industrial protocol to a new controller?

A

Potentially, yes. We first evaluate the protocol stack, operating-system abstraction, hardware interfaces, timing requirements, licensing, and conformance obligations.

Q

Does compilation prove the firmware works?

A

No. Compilation verifies part of the software-development process. Correct operation must be validated on the target hardware and, where relevant, on the physical communication interface.

Q

Can you add remote firmware updates?

A

Yes, subject to available memory, bootloader control, storage, connectivity, security requirements, and acceptable recovery behaviour.
