The Windows operating system is booting normally, the K1297-G20 application is giving timeout and not starting because the boards are not responding. I will post the log file and a screenshot. The problem with the boards is that the boot command, which is stored in the NVRAM. Because the lithium battery has discharged, this parameter was lost. I replaced the component that has the battery (it’s a combination of 2 components a lithium battery and a crystal called SNAPHAT), but now I need to store in the NVRAM the correct boot command line, since now it is just a sequence of bogus characters (on one ofthe tracers it was only a line full of “U” characters, on the other one just some random characters).
