2 years ago It seems due to lack of memory. I have only 16GB RAM only. After adding more 8GB, the error could not allocate 2 gone away but new error comes: Could not get mmap kernel memory!
usec 1000087.875000
Core_id:0
Could not get mmap kernel memory!
nb matches: 0
nb no matches: 0I wonder if it's still lack of memory issue. Can you please tell me how much memory is needed to run Pigasus? Thank you!

2 years ago Hi, thank you for trying Pigasus and for reporting this issue!
This error is actually not due to insufficient memory. The issue is that Pigasus requires CMA to be enabled in the kernel.
The kernel must be compiled with support for CMA and you must preallocate a CMA memory region at boot time.
To allocate a CMA region at boot time, add the following to your /etc/default/grub configuration file.
GRUB_CMDLINE_LINUX="cma=1G"If the option GRUB_CMDLINE_LINUX already exists, append cma=1G to it, making sure there is a space between the existing options and the new ones. For example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash cma=1GB"Then run:
sudo update-grubAnd reboot the server:
sudo rebootImportant. If your kernel is compiled with CMA disabled, you need to recompile the kernel enabling CMA. I found that this answer on StackOverflow gives good instructions on how to do it: https://stackoverflow.com/a/60231594/2027390
Thank you for reporting this. This reminds me that we should add instructions about this to the README, or start using hugepages to avoid the need to recompile the kernel.

Hi, Thank for your work. I'm trying to run Pigasus with our Stratix MX board. I'm able to flash FPGA bit stream, the host recognized the FPGA device as
Howerver, when running Pigagus, I got
Could not get kernel memorymessageI added few printk messages and found that the address is 0
Could you please give few hints on what would be wrong/missing steps?
Thank you!
