Hi,
I was able to view the cache of the armv8 CPU using ARM DS-5. Applying the same steps, i try to view the cache of armv8 CPU using the ARM Development Studio, it throw me an error saying that "Failed to read contents of Internal RAM L1-I_DATA. Please help
My ARM DS version is 2019.1 Build: 201910913
Regards,Boon Khai
Yes. I do have ARM DS gold license
Just installed a windows version and try still no luck
I reply you on the support system with more specific information
Hi Kaiyou,
are you using the DSTREAM debugger? if yes, may i know what is your DSTREAM debugger firmware version? mine is 6. Probably yours is greater than 6 since you are able to run on ARMDS 2020
Yes I use the DSTREAM.
The DSTREAM firmware is 6.0.0-10 when using the ARM DS 2019.1.
The DSTREAM firmware is 7.0.0-6 when using the ARM DS 2020.0
Not trying ARM_DS 2020 yet as this require the update of the DSTREAM firmware. As the DSTREAM is shared among the developers, I'm afraid the update will break other developer's work.
Ok, I'm still gathering the Information and will reply you soon
After contacting arm support.
The CACHE_DEBUG_MODE option some how was not set. To check the option value, at ds command run
$ debug-agent
look for CACHE_DEBUG_MODE option and it will show 0.
set it to 1 and the I'm able to read the cache
$set debug-agent CACHE_DEBUG_MODE 1
interrupt the processor and read the cache.
