Adds ArduinoOTA to the NerdminerV2 env so the firmware and the SPIFFS config can be flashed over wifi: pio run -e NerdminerV2-OTA -t upload --upload-port <ip> pio run -e NerdminerV2-OTA -t uploadfs --upload-port <ip> - 16MB dual-app partition table (default_16MB.csv) for A/B OTA slots. - mDNS hostname nerdminer-<mac4>, advertising fw_version in its TXT record. - OTA password taken from the NERDMINER_OTA_PWD env var at build time; the build fails (static_assert) if it is unset, so no password is committed. - During a transfer the miner tasks idle at a safe point via an ota_active flag and RELEASE the SHA hardware lock first: otherwise suspending a hw miner mid-hash keeps that lock and Update.end()'s image SHA-256 check deadlocks (transfer reaches 100%, device hangs). The monitor and stratum tasks (which don't touch the SHA engine) are simply suspended. - A watchdog task reboots the device if a transfer stalls >90s, since ArduinoOTA.handle() blocks inside loop().

Adds ArduinoOTA to the
NerdminerV2env so both the firmware and the SPIFFS config can be flashed over wifi, no USB needed:Details
default_16MB.csv) for A/B OTA slots.nerdminer-<mac4>, advertisingfw_versionin its TXT record (avahi-browse -r _arduino._tcp).NERDMINER_OTA_PWDenv var at build time; astatic_assertfails the build if it is unset, so no password is ever committed.ArduinoOTA.handle()blocks insideloop().The tricky part: SHA engine deadlock
Suspending a hardware miner mid-hash keeps the SHA hardware lock (
esp_sha_acquire_hardware).Update.end()then callsesp_image_verify(), which computes the image SHA-256 with that same engine → deadlock: the transfer reaches 100 % and the device hangs with no error until the watchdog reboots it.Fix: the miner tasks poll an
ota_activeflag and idle at a safe point with the lock released; in-flight jobs get 300 ms to drain before the (SHA-free) monitor and stratum tasks are suspended. Isolated with anOTA_ONLY_TESTbuild (wifi + OTA only) that always succeeded, which pinpointed the miner tasks as the cause.Note
Switching the env to the 16 MB table wipes SPIFFS on the first USB flash — re-push
config.jsonwith-t uploadfsafterwards (wifi credentials live in NVS and survive). Tested end to end on a LilyGo T-Display-S3: firmware + config OTA both succeed with the miners, screen and stratum all running.
