Assistance Needed: Trouble Running Bare-Metal Code on second core Cyclone 5 HPS
I am working on intel cyclone 5 hps I have two cores in a processor Core 0 core 1, I want two code to run on two different cores core 0 and core 1 in bare metal .
When I run in jtag mode it works, for jtag i first debug using core 0 where i take core 1 out of reset it, than debug core 1 usign jtag it work
BUT, When i want to run both core usign qspi it only run core 0 not core 1
Here is the step i followed
Firsly, loading preloader
quartus_hps -c 1 -o P preloader-mkpimage.bin
I make an image from bin file of core 0 and place it to qspi
mkimage -A arm -O u-boot -T standalone -C none -a 0x00060000 -e 0 -n "baremetal image" -d core0.bin core0.img
quartus_hps -c 1 -o P -a 0x00060000 core0.img
I make an image from bin file of core 1 and place it to qspi
mkimage -A arm -O u-boot -T standalone -C none -a 0x00100000 -e 0 -n "baremetal image" -d core1.bin core1.img
quartus_hps -c 1 -o P -a 0x00100000 core1.bin
When i restart board only that code work which is in core 0, core 1 code not executing
I am setting cpu1startaddress 100000 apart from that in the code of core 0 also i am using alt_qspi function to to place bin file data in ddr,
I want to run in smp mode so I also set required aux_control_register smp and fw bit as stated in tech ref manual
alt_qspi_read((uint32_t *)BL_START/*ddr3 address*/, 0x100000/*qspi address*/, 0x40000);
In linker/scat file core 0 entry point is 0x60000 and
linker/scat file core 1 entry point is 0x100000

@JingyangTeh_Altera then please provide me with any project similar to my issue, that is handling multiprocessing of dual-core at bare-metal level of any intel soc. I'll manage the configuration according to my board. Waiting for your quick and timely action.

Hi
We do not have any example design for running application on separate core.
However we do got an example design which uses the Nios II processor as a separate core solution.
