Part Number:AM5718
Tool/software: TI-RTOS
I have custom board based on AM5718 and now developing custom bootloader and application based on TI-RTOS with video capture and HDMI display functionality using source code from pdk_am57xx_1_0_14.
I use idkAM571x board as a reference and debug platform. I have some troubles running VPS Loopback Example on idkAM571x board. Project was created using pdkProjectCreate.sh script and built with Code Composer Studio 8.3. When loading example with JTAG everything works just fine, I can see picture from camera on external mini-board on HDMI display.
But it hangs when booting from MicroSD card. I tried to use precompiled bootloader pdk_am57xx_1_0_14/packages/ti/boot/sbl/binary/idkAM571x/mmcsd/bin/MLO. This bootloader loads and runs app, but executions stucks in LpbkApp_init function with debug output "hal/src/vpshal_dssDispcOvly.c @ Line 2880: DSS Still in reset".
It seems that GEL files through JTAG setup something inside display subsystem of AM5718 which booloader does not do. Please tell me what can that be?
Regards.
