Прошил чисто на питании от программатора, прошивка прошла успешно, по крайней мере в догах н каких проблем я не увидел, но при подаче питания блок всё так же не подаёт признаков жизни, после прошил ещё раз но уже от питания двенадцати вольтовым аккумулятором, результат тот же.
Возможно я чего не доглядел, вот мои логи.
