Now I am using I.MX6UL development board named "i.MX6UltraLite Evaluation Kit (EVK)" . what i did is:
1: Install SDK_2.2_MCIM6UL on my PC.
2: Build one standalone elf executable file with demo IAR project in SDK folder “C:\nxp\SDK_2.2_MCIM6UL\boards\evkmcimx6ul\driver_examples\gpt\capture”.
2: press any key to stop auto-uboot, with uboot version "uboot-imx-imx_v2016.03_4.1.15_2.0.0_ga".
3: load elf file via command bootelf
=> fatload mmc 1:1 0x80800000 gpt_capture.out
217948 bytes read in 35 ms (5.9 MiB/s)
4：Boot elf from memory.
=> bootelf 0x80800000
And my question is
1: Any idea why demo binary file execution is stuck? Assume application timer should start ticking.
2: How to disable interrupts initialized by U-boot? I mean how to diasble intterupts before bootelf command.
Thanks for the help in advance!
