Merge pull request #34 from mithro/uart-irq-change
Change the default IRQs.
2017-10-30 13:54:19 -07:00
Tim 'mithro' Ansell 56ef229029 Make the interrupt dicts read only. 2017-10-29 19:45:52 -07:00
Tim 'mithro' Ansell 295e78ee9e Make it harder to have conflicting interrupts. 2017-10-29 19:45:52 -07:00
Tim 'mithro' Ansell ff72757b87 Bump the IRQ for liteeth based targets. 2017-10-29 19:45:52 -07:00
Tim 'mithro' Ansell 73e0036b99 Change the default IRQs.
* Reserve IRQ 0 to be used as a "non-maskable interrupt" (NMI) in the
   future.

 * Use IRQ 2 for the LiteX. This matches the standard mor1k config which
   connects the UART to IRQ 2.

This change is needed for Linux running on LiteX as it gets grumpy with
using IRQ 0 for anything other other than an NMI.
2017-10-29 19:45:52 -07:00
Tim 'mithro' Ansell e07bd71b16 build/xilinx: Fixing settings finding.
* Better error messages.
 * Search correct directories;
   - XXX/Vivado/<version>
   - XXX/<version>/ISE_DS/

Florent Kermarrec db6c88bbef soc/interconnect/stream: don't use reset less on last and first signals (not reseting these signals can cause troubles in some specific cases) 2017-10-12 11:30:56 +02:00

Tim 'mithro' Ansell 279ec488e3 bios: Print location jumping too.
Makes it easier to  understand what is happening (and that the BIOS is
jumping to the right place).

Tim 'mithro' Ansell 8152673d18 common: Compile with debugging symbols on.
Debugging symbols are useful when using GDB :-)
2017-10-06 20:38:44 +11:00
Tim 'mithro' Ansell b1b6a74170 or1k: Use EXCEPTION_STACK_SIZE of 256bytes.
or1k defines a 128 byte "red zone" after the stack that can not be
touched by the exception handler.

We also need 128 bytes to store the 32 registers.

Florent Kermarrec 9509d9e361 gen/genlib/cdc/gearbox: fix possible pointers overlap by removing AsyncResetSynchronizers.
read/write clocks don't have the same frequencies, using AsyncResetSynchronizers cause differents delay when releasing reset and can cause pointers overlap.

Add Diamond toolchain support for Linux.
2017-07-20 14:41:05 +02:00
Sergiusz Bazanski 503df5e93e Add Diamond toolchain support for Linux.
This tries to replicate the same setup as in the Windows buildsystem. We
also remove the Jedecgen step, as it doesn't seem to be supported nor
necessary in newer versions of Diamond.
