Hi,
I am quite new in SoC development and I would like to ask for some guidance.
We build custom board based on 5CSEBA5U23I7S.
I compile Preloader/Uboot/Kernel/DevTree/RootFS and create sdCard for first boot.
But I would like to ask how can I start to debug first BootRom and preloader initialization steps.
I tried to use DS-5 the same way as it is in Workshop labs on rocketboards.org but I cannot connect to HPS.
"Failed to connect to the device
Unable to connect to the device Cortex-A9_0
Failed to write register 0 on device CTI_0_2
General error on memory or register access"
We have direct output for HPS jtag and I can see HPS device in Quartus programmer through Altera USB blaster.
Secondly we have UART/RS485 transfeiver connected to HPS UART0 but I guess uart needs to be first initialized to stream some output.
Could you help me to find possible way to get some output I can start to debug Preloader->Bootloader->OS->etc. Some listning I can stick to and step by step debug it.
Thank you very much,
Michal
