bunnie d892c6f8f5 minor bug fixes in spi writing; USB-based flashing is not working 2020-11-07 03:57:46 +08:00
Florent Kermarrec 9359aa0688 tools/litex_server: revert CommUDP's max length to 4 now that https://github.com/enjoy-digital/liteeth/issues/52 is fixed). 2020-11-06 19:50:25 +01:00
Florent Kermarrec 9fe3a42072 software/liblitedra/sdram: minor cleanup, use identical delay after each delay increment. 2020-11-06 16:11:25 +01:00
Florent Kermarrec d1ef64f9fd tools/litex_server: revert CommUDP's max_length to 1. 
https://github.com/enjoy-digital/liteeth/issues/52 needs to be investigated before enabling _read_merger
on UDP.
 2020-11-06 13:01:56 +01:00
Florent Kermarrec 996be95725 tools/litex_sim: also add CPU's dbus to analyzer_signals (to demonstrate triggers in wiki). 2020-11-06 12:49:43 +01:00
bunnie fc59bcd833 add facility for burst writing and fix pp4b command bug 2020-11-06 04:43:23 +08:00
Florent Kermarrec 61c009a393 revert get_data_mod change (Vexrisv SMP repo has been renamed to pythondata-cpu-vexriscv_smp). 2020-11-05 19:55:18 +01:00
Florent Kermarrec c088cd5d22 cores/clock: only use locked on AsyncResetSynchronizer (already falling on reset) and add delay to reset to prevent interlocks with BIOS reboot command on Xilinx devices. 2020-11-05 19:43:11 +01:00
Florent Kermarrec 3e47a6e48b get_data_mod: fix error message when module not found (pythondata modules are named only with "-" and not "_"). 2020-11-05 15:58:32 +01:00
Florent Kermarrec 65f19b5c4a integration/soc/add_sdram: add with_bist parameter to add LiteDRAM's BIST. 
sdram_bist command will then be available in the BIOS:

litex> sdram_bist
sdram_bist <burst_length> <random>
litex> sdram_bist 256 0
Starting SDRAM BIST with burst_length=256 and random=0
