Overview

Tang Mega 60K uses the 22nm process GW5AT-LV60P484A FPGA chip with 59904 lookup table units and 118 DSP units. It contains four high-speed transceivers with speeds ranging from 270Mbps to 6.6Gbps, which is suitable for transmitting data on high-speed ports such as PCIe. In addition, the chip contains hard-core PCIe and MIPI C/D PHY controllers, which consume better resources and get better performance when using PCIe. It is suitable for high-speed communication, protocol conversion, high-performance computing and other occasions.

The 60K Dock and 138K Dock share a set of dockboards(TANG MEGA NEO), so the peripherals of the two are exactly the same. Compared with the 138K Dock, the 60K Dock has fewer logic resources and a lower price, and includes a MIPI C/D PHY transceiver. This not only further reduces the cost of high-speed communication, but also brings better compatibility for image processing system integration.

Hardware Resources

Getting Started

Note that 60K is currently not supported by the education version, and you need to download V1.9.10.01 or a newer version of the commercial IDE for use.
There are serious problems with the Programmer version V1.9.10.02, and this product cannot be programmed.
Lic can be applied on the Gowin official website, or you can use the online Lic service provided by Sipeed. In the IDE, select Float Lic and fill in the following information:

ip: 106.55.34.119
port: 10559

if the ip not work, try use "gowinlic.sipeed.com" domain's IP.

Precautions

Item Precautions
Chip Model The specific model of the FPGA chip used by Tang Mega 60K is GW5AT-LV60PG484A

Please select the package model PBG484A in the IDE.
Static Electricity Please avoid static electricity hitting the PCBA; release the static electricity from your hands before touching the PCBA.
Tolerance Voltage When using GPIO pin headers for external communication, ensure that the IO voltage is 3.3V. Excessive voltage will permanently damage the PCBA.
FPC Socket When connecting the FPC soft cable, please ensure that the cable is completely and correctly inserted into the socket without any deviation.
PCIE Gold Finger When testing the PCIE gold finger, ensure that both the host and the board are in the off or unpowered state to avoid short-circuiting the gold finger due to displacement during the insertion process.
Plug and Unplug Please completely power off before plugging and unplugging.
Avoid Short Circuit Please avoid any liquid or metal touching the solder pads of the components on the PCBA during the power-on process, otherwise it may cause a short circuit and burn the PCBA.

Frequently Asked Questions (FAQs)

After powering on the board, only four indicator lights on the dockboard are on, the SOM indicator light is not on

  1. Please check if the board’s power has been turned on, press and hold the PWR button (next to the HDMI port) for 2 seconds to turn on the power.

After powering on the board, the Battery-Indicator light on the dcokboard is flashing

  1. This is normal behavior, usually, the last LED (near the 12V DC connector) is flashing;
  2. When the board is connected to a 3.7V lithium battery, these LEDs will serve as battery level indicators.

After pressing and holding the PWR button for 2 seconds, all the indicator lights on the dockboard turn off and then light up in sequence

  1. Check your power supply method, this situation means that the power supply is insufficient;
  2. Solutions (choose one):
    a. Connect both the board’s USB-3.0 and USB-DEBUG for power supply, i.e., dual 5V USB power supply;
    b. Connect a 12V DC power supply to the board, if using the USB-C to 12V DC connector from the accessories, a PD power source with 12V output capability is required;
    c. Connect a 3.7V lithium battery to power the board, note that the battery voltage must be ≥3.6V and the continuous discharge capacity must be ≥600mA.

IDE cannot find the model GW5AT-LV60PG484A

  1. The educational version does not support 60K, please switch to the commercial version. The following image shows the educational version (which does not support 60K);
  1. IDE version is too low to use, update the IDE version ≥ 1.9.9.

How to burn the bitstream to FLASH

  1. Setting the Programmer as shown in the figure below:
flash_mode
  1. Check the position of the DIP switch; the correct position is shown in the figure below:
dip-key_defualt

No Response or Undesirable Pin Phenomenon After Burning

  1. First, ensure that the IDE has selected the correct model GW5AT-LV60PG484AC1/10; every parameter in the figure below MUST be consistent.
device_choose
  1. Then, check your code and the corresponding simulation waveforms to meet the requirements. The GAO tools in GOWIN IDE maybe helpful. For more information, please refer to the GOWIN document SUG100(require login).
