Precautions
Attentions in use of the development board:
1.
Handle with care and pay attention to electrostatic protection;
2.
Before downloading from FPGA and MCU, switch SW3
、
SW4
、
SW5
、
SW6 to the FT232 side;
3.
Before MCU Debugging, switch the SW3, SW4, SW5, and SW6 on the
development board to J-Link side;
4.
VCCO2 Bank voltage needs to be set as 2.5V via changing J3 jumper
position when the Bank2 output differential pairs serve as LVDS output;
VCCO2 Bank voltage needs to be set as 1.2V via changing J3 jumper
position when the Bank2 output differential pairs serve as MIPI output.
5.
Bank voltage needs to be set as 2.5V via changing J9 jumper position
when Bank1 differential pairs serve as LVDS; Bank voltage needs to be
set as 1.2V via changing J9 jumper position when Bank0 differential
pairs serve as MIPI I.
6.
GW1NSER-4C is GOWIN SecureFPGA with Secure Mode and
Authentication Code.
7.
Gowin version1.9.5 and above is required to develop the
GW1NSER-4C device.
8.
Carefully use the “Secure Mode" of one-time programming for product
delivery. During factory debugging, it is recommended not to use the
"Secure Mode" of one-time programming and the Secure FPGA can be
programmed and downloaded repeatedly.
9.
Before using the development board for the first time, read back the
authentication code and save to your local PC using Programmer.
Write the authentication code first each time before downloading the
MCU code.
10.
For the device of GW1NSR-4C or GW1NSER-4C, PSRAM power
supply is provided via VCCO3 Bank voltage.
11.
For the device of GW1NSR-4C or GW1NSER-4C, Pin47 and Pin48 are
not differential signal.
