I upgraded Ard IDE from 1.8.13 to 1.8.19 by complete reinstall 1.8.19 from scratch. I kept the old1.8.13 ( MAC OS). The new IDE can not compile ulp examples for not finding references to ulp symbols such as urp_entry etc. Since I still have the old 1.3.13 I can use it and it works with very same ulptool/esp stuff in /Library/Arduino15/...
When I replace the bin file arduino-builder in 1.3.19 installation by the old one everything is fine, means the problem is created by incompatibility of arduino-builder with the rest of the data. Any idea why ?
