Linux of A72 running vck190

1. System Controller

VCK190 On the board , There is one MPSoC chip ZU4EG, As a single board management chip (System Controller).

1.1. System Controller SD(TF) card

Start up VCK190 Before , for ZU4EG Ready to start TF card . The document says SD card, It also means TF card .

Xilinx Provides a TF The image file of the card ,Board_Framework_Phase1Beta_V1.02_wVadj.img, The size is 15,931,539,456 bytes, Need to use Win32 Disk Imager Write to 16GB Of TF card .

although TF The capacity of the card may be nominal 16GB, The actual capacity may be different . There are some TF The card is too small , Less than 15,931,539,456 bytes,Win32 Disk Imager Will report a mistake .

To solve this problem , You can put Board_Framework_Phase1Beta_V1.02_wVadj.img The rest is discarded . For example, use the following command “dd if=./Board_Framework_Phase1Beta_V1.02_wVadj.img of=./Board_Framework_Phase1Beta_V1.02_wVadj_Small14G.img bs=1000 count=14M”, Only about 14GB The content of , You can write to 16GB Of TF It's Cary .

xilinx:/mnt/prj/versal/vck190/$ dd if=./Board_Framework_Phase1Beta_V1.02_wVadj.img   of=./Board_Framework_Phase1Beta_V1.02_wVadj_Small14G.img  bs=1000 count=14M

Use Win32 Disk Imager burning TF Card time , Best to windows Run with the administrator rights of , Turn off irrelevant Software . such as “explore ++” It will lead to Win32 Disk Imager burning TF The card failed .

burning TF After the card , hold TF Card insertion VCK190 At the bottom of the veneer J206.

1.2. System Controller boot mode DIP switch SW11

Then set the startup mode .ZU4EG The start mode switch of is SW11, stay HDMI(Ethernet) Between the socket and the fan . System Controller Use TF Card activation ,SW11 Set it to 0001(1=on, 2,3,4=off). System Controller After starting , Serial port display Linux Start information for ; After startup , Can't enter command .

1.3. VCC_AUX

The System controller(ZU4EG) adopt PMC MIO37 open VCC_AUX. PMC MIO37 Must be in Vivado In our project , Set to :

  1. Peripheral: GPIO
  2. Output Data: High
  3. Direction: out

2. function VC1902 Of A72 Of Linux

VCK190 The main chips on the board are VC1902.VC1902 The processor part of IP It's called CIPS.

2.1. SD card J302

VC1902 Start of SD(TF) The card socket is J302, stay VCK190 On the front .

2.2. COM port J207

VCK190 Through the serial port of USB Type-c J207 The connector goes out , stay PCIe Metal baffles (PCIe bracket) middle , It may need to be removed PCIe Metal baffles , In order to fully connect .

2.3. boot mode DIP switch SW1

VC1902 The start mode switch of is SW1, In the power socket and DIMM Between , stay PCIe Opposite the golden finger . VC1902 Use TF Card activation ,SW1 Set it to 0111(Up,Down,Down,Down; ON, Off, Off, Off). among Up Express 0. VC1902 Other mode settings are as follows :

Supported boot mode setup SW1: (Up == 0;Up == ON; pin 1 to pin 4) 
0x0 - "0000" - JTAG (All up) 
0x2 - "0100" - QSPI_32 (Up,Down,Up,Up) 
0xE - "0111" - SD – (Up,Down,Down,Down; ON, Off, Off, Off)
