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.
