Linux+new IP core design flow

Hi all:
We have modified Demo project and have added our IP which is generated by VivadoHLS. In SDK, we have also generated FSBL and created the boot.bin (fsbl.elf+system.bit+u-boot.elf).
For creating FSBL we modified the ClearFSBLIn as Xilinx mentions in his forum.
void ClearFSBLIn(void) {
FsblOut32(REBOOT_STATUS_REG,
        (FsblIn32(REBOOT_STATUS_REG) & ~FSBL_IN_MASK) &
t~PARTITION_NUMBER_MASK);
}

When the board starts, doesn't load all linux. It halts in line
[    0.560000] ---[ end trace 1b75b31a2719ed1e ]---
or
[    0.630000] [<c000e1d8>] (cpu_idle+0x38/0x9c) from [<00449b14>] (0x449b14)
But it never load all system.
Do we have to recompile The Kernel Linux to include new IP's drivers or can we load the drivers later?

Ty for help.

Hi Peaceo,

Is this the forum post that you are referring to?

http://www.xilinx.com/support/answers/50499.htm

Have you built your Programmable Logic IP as part of a PlanAhead project that contains an embedded PS subsystem?

If this is not being done (maybe you are using a Project Navigator only flow) then Linux will not finish booting after loading your PL bitstream. Even if your custom logic is not attached to the AXI interface, adding that embedded PS subsystem will add some configuration for the PS-to-PL interconnects which will allow Linux to boot all the way up.

If you are unsure of how to create an embedded PS subsystem in your PlanAhead design, take a look at the "Zynq Concepts, Tools, and Techniques on ZedBoard v14.1" project in the Reference Design section.

Also, can you please post additional lines of Kernel terminal output leading up the point where you see the boot process freeze?

Regards,

-Kevin

Yes, I obtained the modified in this forum "http://www.xilinx.com/support/answers/50499.htm"

The project was generated in EDK 14.2 (Xilinx Platarform Studio) and was implemented and exported to SDK plataform where we generatedfsbl and .bit

Following your suggestions we instanciated the edk project in Planahead 14.2 as subsystem, the implementation shows the following 3 critical warnings:

[Constraints 18-5] Cannot loc instance 'processing_system7_0_PS_PORB_pin_IBUF' at site B5, Site location is not valid ["C:/ProjectXilinx/ZedBoard/PlanAhead/mcdma_mmult_clean/implementation/mcdma_mmult_processing_system7_0_wrapper.ncf":158]

[Constraints 18-5] Cannot loc instance 'processing_system7_0_PS_SRSTB_pin_IBUF' at site C9, Site location is not valid ["C:/ProjectXilinx/ZedBoard/PlanAhead/mcdma_mmult_clean/implementation/mcdma_mmult_processing_system7_0_wrapper.ncf":159]

However, the implementation finished. The project was downloaded to Zedboard (using SD), but we got the same error during the linux boot:
See errors in [    0.550000] and [    0.870000].
