I want to know about serial downloader mode.
Please let me know the following questions.
I plan to build a custom board with i.MX6UL and eMMC which is for boot device.
Unfortunately, the custome board have only UART for serial download.
According to the following thread, i.MX6UL support USB_OTG and UART1/2 in serial downloader mode.
So I want to test serial downloader with UART in MCIMX6UL-EVK.
Can user test UART serial downloader mode in MCIMX6UL-EVK ?
I found a source code for UART serial downloader mode and tested it.
But it faild booting.
Does someone test the source code ?
If yes, please let me know the check point to solve it.
If i.MX6UL can't support UART serial downloader mode, we plan to use JTAG for write to eMMC.
Do you have any other recommendation except using JTAG ?
If i.MX6UL can't support UART serial downloader mode, we have to think other way for writing image to eMMC.
This will be problem for verification at the time of mass production and development.
Please hellp me.
