刷了新bootcode之後的遙控開機問題

可藉 TTL 進入 monitor mode 來修改,例如:


?hello world!
5280 w5ai28t0 waiA[HDMI]: Set I2C Speed = 100 kHz

[HDMI]: Chk_HotPlug() TV is not connected.

[HDMI]: Read_EDID abort, HDMI cable plug off.

[HDMI]: TV is not connected.

補充 : 1026L Bootcode 的問題

HD-A5 刷了 1026L Bootcode 之後,刷各種SDK3 韌體都沒有問題,刷像 ACRBO 的 SDK4 韌體也都沒有問題,但是刷上海版 SDK4 韌體則會停在開機畫面,原因不清楚。
