I was able to debug uboot w/ jtag using openocd 0.11 on the imx8mp. (Previous to 0.11 required patches but it seemed to work find now as there is an included profile for the imx8mp-evk board.) Here are some relevant links from other posts and some discoveries. 1) http://fatalfee...
The SOM successfully boots u-boot from SD Card and Linux on eMMC, with 8GB of DDR4. I have done many tests and the CPU cores, memory, eMMC and USB3 appear stable. We have however massive trouble getting any of the SERDES functions to work. The lane setup is B8BE, PLL ...
When I do this, the .config file in the build directory reverts to the default config (not my altered version) and the resulting u-boot binary doesn't have the change (boot delay still 3 sec). I think my layer is getting processed because I see this in the output: DEBUG: Appending ...
So I was trying to find if the linux kernel uses the u-boot serial driver to print and get characters. As already mentioned, the Linux kernel will not execute code outside its own image. However there is the "low-level kernel debugging" feature (CONFIG_DEBUG_LL and its...

To make sure we understand you correctly. You want to program u-boot to the RAM of imx6ull using one of our tools? U-boot is not our software so we can't provide any images for that. But if you have an image already you can simply load it using J-Link Commander using the "...
To implement this Timing Diagram, you need to use the mode of the sspi command. However, in the default uboot, the mode of the sspi command that succeeded the first time is to be used continuously in the next command, and the mode cannot be changed by...

arch/arm/boot/decompressed/head.S,the kernel runs and stopsat"Uncompressing Linux... done, booting the kernel." No, that's just the last thing it output. I seldom find other people's debug code useful. I stick a printf()variant in the code at a place I want to see what it's doi...
