that all sounds wonderful... But reading from those addresses does generate an exception, so the DSP "knows" that they are invalid? I looked at some of the registers and the...

@aborisovich @marc-hb @keqiaozhang any progress with this? We really want sparse support in CI - we get code added regularly that involves buffer manipulation and having an automated check for...

> @lyakh have you tried `-DSPARSE=y` with the most recent container and 0.15.0 toolchain? I haven't, but have you also set the env variable? I.e. ``` export REAL_CC=${HOME}/zephyr-sdk/xtensa/intel_s1000/xtensa-zephyr-elf/bin/xtensa-zephyr-elf-gcc ``` I...

@marc-hb also, looking at the error log above - is the path `/opt/toolchains/zephyr-sdk-0.15.0/xtensa-intel_s1000_zephyr-elf/bin/xtensa-intel_s1000_zephyr-elf-gcc` actually there?

@marc-hb do I understand it correctly, that all your "sparse" questions are now resolved with #6232 and #6238 ?
