To resolve the “make[5]: /bin/sh: Argument list too long” error The “Argument list too long” error occurs when the command line arguments exceed the system’s limit.

The Latest AMD Ryzen 7985WX for Yocto Build About four years ago, our company purchased an AMD Ryzen™ Threadripper™ 2990WX with a 32-core CPU for Yocto builds. At that time, using all the cores for building was unstable—the build would freeze, and the PC would crash, so we couldn’t utilize the full 32 cores and 64 threads and had to settle for using only about half. Ultimately, that PC broke down a month ago, and we now find ourselves in ..
Weekly - CW45 (Nov 4 ~ Nov 10) This week has been packed with meetings. Maybe it’s because of the nature of my work lately, but my day now starts with meetings from 8:30 in the morning. Since I’m collaborating with teams in China and India, most of the meetings are scheduled in the morning, which gives me some focused time in the afternoon. However, most of that time ends up being used for follow-up work from the morning meet..
