Досталось 2 16-ти канальных регистратора на базе MBD6016E-E (отличие только корпусов), чип HI3531.
Первый регистратор работал нестабильно, перезагружался хаотично. Была залита прошивка по совету продавца. Результат - полное отсутствие видео на каналах. Загружается в штатном режиме. Заливка других прошивок для платформы MBD6016E-E положительного результата не принесло. Я сделал дампы c рабочего регистратора с 16 мб флешки (MX25L12845EMI-10G) из telnet'а:
mtdblock0 (512 kb) - boot, загрузчик u-boot 0x82000000
mtdblock1 (4096 kb) - romfs, romfs-x.cramfs.img
mtdblock2 (5632 kb) - usr, user-x.cramfs.img
mtdblock3 (1536 kb) - web, web-x.cramfs.img
mtdblock4 (3072 kb) - custom, custom-x.cramfs.img
mtdblock5 (256 kb) - logo, logo-x.cramfs.img, логотип при загрузке
mtdblock6 (1280 kb) - mtd
Подскажите пожалуйста, как правильно через UART записать блоки дампов (1-5), по каким адресам заливать, чтобы загрузчик не тронуть?
