Hello,
Hard configuration
I.MX 7 Dual SABRE Board + IMXEBOOKDC4-EPD
OS / Kernel
Android 7.1.1
Kernel 4.1.15
Building android for imx7 based on Android User's Guide, the following will be created
boot-imx7d.img / boot-imx7d-epdc.img
recovery-imx7d.img / recovery-imx7d-epdc.img
u-boot-imx7d. imx / u-boot-imx7d-epdc.imx
system.img
Images for EPD and LCD are created.
(Why do you understand separately?)
boot-imx7d-epdc.img. recovery-imx7d-epdc.img. u boot-imx7d-epdc.imx. system.img
After writing the above file to SD, Android started, it was displayed on EPD.
Next, in order to display on the dual display of HDMI and EPD,
It changed to the following of imx7d-sdb-epdc.dtsi.
& Sii902x {
Status = "okay"; Before modification: disabled
};
& Lcdif {
Status = "okay"; Before modification: disabled
};
I corrected the above and created boot-imx7d-epdc.img, recovery-imx7d-epdc.img, u-boot-imx7d-epdc.imx again.
I wrote Android to SD but I could not display EPD or HDMI.
Do you know what caused the problem?
(I attached the log)
