CHERECHEDZA: 

1. ita shuwa kuti i2c-1 driver point yakavhurika, uye poindi yacho yakavharwa default.
2. iyo inofungidzirwa kuchengetedza nguva yeRTC mazuva gumi nemashanu.

Chigadzirwa Chekuchinja CHERECHEDZA:

OLD Ongororo: Iyo chip yeRTC ndeye MCP79410 kubva ku microchip. Yakaiswa pane system I2C bhazi. I2c kero yeiyi chip inofanira kunge iri 0x6f. Kuigonesa unofanira:

Vhura /etc/rc.local UYE wedzera mitsara miviri:

echo "mcp7941x 0x6f"> /sys/class/i2c-adapter/i2c-1/new_device hwclock -s

Wobva wagadzirisa zvakare system uye RTC iri kushanda

UPS yekuvhara zvakachengeteka (Inosarudzika)

Iyo UPS module dhizaini yakanyorwa pazasi.

Iyo UPS module inoiswa pakati peDC5V neCM4, GPIO inoshandiswa kuridza CPU kana simba re5V radzika. Ipapo iyo CPU inofanirwa kuita chimwe chinhu nekuchimbidza mune script isati yapera simba repamusoro capacitor uye kumhanya "$ shutdown" Imwe nzira yekushandisa basa iri Tanga kudzima kana GPIO pini yachinja. Iyo pini yeGPIO yakapihwa inogadziriswa sekiyi yekuisa iyo inoburitsa KEY_POWER zviitiko. Ichi chiitiko chinobatwa ne systemd-logind nekutanga kudzima. Shanduro dzeSystem dzakakura kupfuura 225 dzinoda mutemo weudev unogonesa kuteerera kune mudziyo wekuisa: Shandisa /boot/overlays/README sereferensi, wozogadzirisa /boot/config.txt. dtoverlay=gpio-shutdown, gpio_pin=GPIO22,active_low=1

CHERECHEDZA: 

1. Nezve UPS basa ndapota taura nesu kuti uwane rumwe ruzivo.
2. Chiratidzo chearamu chiri kushanda LOW.
