===== Boot Procedure =====

After complete power cycle all AFCs should boot itself.
Before CPU is going to boot MATPEX card need to be enabled.

Login to sdlx008.acc.gsi.de over SSH and connect to MCH console
<code>
#Left MCH
screen /dev/ttyACM0 19200   (STRG A + STRG D to detach vom screen)
#Right MCH
screen /dev/ttyACM1 19200
</code>

List all FRU using command **show_fru**

MATPEX occupies slot AMC2 (fru id 6)

After typing **fru_start 6** MATPEX should go into state **M4**

After all modules are running you may enable CPU using command **fru_start 5**



==== FPGA boot/reset ====

Login to sdlx008.acc.gsi.de over SSH and check if hw server is running.
If not type: 
<code>
/opt/Xilinx/HWSRVR/2017.1/bin/hw_server
</code>

Open VivadoLab 2017.1
Open Hadware Manager session
connect to sdlx008 jtag server

download scansta JTAG switch script [[https://raw.githubusercontent.com/qermit/AfcJtag/master/scansta_afc.tcl]]
<code>
source AxiJtag/scansta_afc.tcl
connect_hw_server -url sdlx008.acc.gsi.de:3121
scansta_enable_all
</code>

From FPGA context menu (right mous click on xc7a200t) select **Boot from configuration memory**

CPU need to be rebooted after FPGA boot.


==== FPGA paritial reset ====

Connect over JTAG to a module, probe file required


===== AFC 3.1 MMC Programming HowTo =====


=== MMC: ===

Install LPCXpresso on Linux PC.

LPC_Link (1) on table with AFC on table

USB Cable connected to PC and LPC_Link

{{:ds:projects:cryring:20200205_144018.jpg?400|}}

dedicated cable from Piotr to JTAG in the middle of AFC with cables heading to FMC connectors

on LPC Link J4 left row with Black = Pin15

enter command on Linux PC:

dfu-util -d 0x0471:0xdf55 -c 0 -t 2048 -R -D /usr/local/lpcxpresso/lpcxpresso/bin/LPCXpressoWIN.enc

=== AFC Firmware (Sirius): ===


Before any FPGA configuration can be performed, you need to switch SCANSTA JTAG switch. Untill than FPGA won't be visible in Vivado. You will find instructions {{ :ds:projects:cryring:afc_afck_scansta_guide.pdf |here}}

jtag_scansta.tcl (TCL-Script):

<file>
#set JTAG */xilinx_tcf/Xilinx/*
set JTAG */xilinx_tcf/Digilent/*

catch open_hw
catch {connect_hw_server -url localhost:3121}
get_hw_targets
current_hw_target [get_hw_targets $JTAG]
set_property PARAM.FREQUENCY 3000000 [get_hw_targets $JTAG]
catch {open_hw_target -jtag_mode 1}

run_state_hw_jtag reset

Flash Chip on AFC 3.1 for FPGA Firmware: mt25ql256-spi-x1_x2_x4

To add click with right mouse button on FPGA in Vivado Hardware Manager:


{{:ds:projects:cryring:1fpmfaokmedhlmjdm.png?400|}}



Then select the right SPI flash:


{{:ds:projects:cryring:2mgfjnodfapnggfji.png?400|}}


You will be asked if you want to program configuration memory device. You can cancel it as MCS configuration file must be generated first.

To generate MCS configuration file select Tools -> Generate Memory Configuration File...

In the window please select right Memory Part, Filename (it's output file name) and tick that the file is to Load bitstream files. Then in the Bitfile input select your bitstream and click OK:


{{:ds:projects:cryring:3ajacbmiiffbcdncp.png?400|}}


To program SPI flash click on the mt25ql256-spi-x1_x2_x4 in Hardware Manager tree and select Program Configuration Memory Device...


{{:ds:projects:cryring:4kpgcemgabkpjonpm.png?400|}}


In the configuration window select created Configuration file and click OK:


{{:ds:projects:cryring:5fknakblnoicfbhne.png?400|}}


SPI flash will be erased and programmed with new gateware.
