My Aruba 500 access point refuses to complete its startup sequence. It reboots repeatedly, flashes an error message on the console, then starts over. I can confirm that an error appears, but I have not yet identified whether it points to firmware corruption, a hardware fault, or a configuration issue. I need an Aruba-certified specialist who understands the unit’s different operating modes, recovery options, and console commands to: • Pinpoint the root cause of this boot failure by reviewing the current console output and any logs we can extract • Guide (or remotely perform) the correct recovery procedure—whether that means flashing new firmware, adjusting boot variables, or restoring a clean configuration • Verify the AP comes back online, joins the co...

Firmware Adaptation for CH591 From CH592

Preciso desenvolver um Módulo de Distribuição de Energia com 18 saídas, inspirado nos PDM15 que já uso como referência interna. O objetivo é assegurar três funcionalidades cruciais desde a primeira versão: proteção contra sobrecarga em cada canal, monitoramento remoto em tempo real e controle individual de todas as saídas. Quero comandar e visualizar tudo numa interface web amigável, acessível tanto em desktops quanto em smartphones; portanto, a parte de firmware e a camada de software devem expor servidores HTTP-REST ou WebSocket que facilitem integrações futuras. Ainda não defini requisitos de compatibilidade com sistemas externos, então o código e o hardwar...

I need production-ready firmware for an STM32F303 that turns the microcontroller into a front-end for high-speed digitisation of SDR signals. The chip’s ADCs must sample the incoming RF-baseband stream, move the data through DMA with minimal latency, and prepare it for onward transmission over a fast serial link (either SPI or UART—whichever achieves the cleanest, sustained throughput on this part). The core of the job is sensor-style data processing: capture, buffer, and pre-format the raw samples so that an external host can handle the heavier DSP. No motor-control, no classic temperature or pressure sensors—just clean, reliable handling of SDR-grade analogue input. Key expectations • Continuous, gap-free acquisition at the highest practical sampling rate for t...

I have a pumping system that needs an intelligent, multi-channel controller capable of switching a 220 V load while staying online almost anywhere. The hardware shortlist is already in place, but I want an experienced engineer to turn that list into a fully working unit that can be triggered three ways: Wi-Fi (802.11n), 4 G LTE, and—when nothing else is available—through a Starlink connection routed from the controller’s Ethernet port. Here is what I need from you: • Electronic design: finish the schematic around my existing parts list, size the power supply for 220 V, choose the right relays/solid-state switches, and ensure the radio modules do not introduce interference. • Firmware: write clean, well-documented code that listens simultaneously for Wi-Fi and...

I’m on a Lenovo ThinkBook 15 G ITL that was running perfectly until the latest update to Ubuntu 22.04 (and now 22.10 on a second partition). Since the update the wired network port is dead—no NIC detected, no lights, nothing. I have NOT downloaded anything from Lenovo yet, so we can start clean. What I need is: • Finding the exact Ethernet driver (or kernel module/firmware) that matches this model for Ubuntu 22.04 + • Installing it safely, with clear commands or a .deb/driver package I can keep for future reinstalls • Post-install troubleshooting if the first attempt doesn’t bring the interface up (dmesg checks, modprobe tweaks, blacklist edits, etc.) Acceptance Criteria – The Ethernet interface appears in `ip link` / `lshw -C network` wi...
