Description

The MYD-JA5D4X Development Board is a complete evaluation platform for Atmel’s ARM Cortex-A5 based SAMA5D42 or SAMA5D44 processor which is among the SAMA5D4 MPU series and can operate at up to 600MHz. Compared to the previous Cortex-A5 SoC from Atmel, the SAMA5D3, the SAMA5D4 brings a L2 cache, NEON, a slightly different clock tree, a hardware video decoder, and Trustzone support. The MYD-JA5D4X board is built around MYIR’s MYC-JA5D4X CPU Module and has a specific designed base board which takes full features of SAMA5D4 SOC to extend a rich set of peripherals and interfaces including serial ports, two USB Host ports, one Mini USB Device port, two 10/100Mbps Ethernet ports, RS485, TF card slot, Audio in/out, HDMI, LCD and more.

MYD-JA5D4X Development Board


The MYC-JA5D42 and MYC-JA5D44 CPU modules are sharing the same circuit design with only minor CPU feature difference. The Atmel SAMA5D44 can support 720p resolution hardware video decoder while the SAMA5D42 cannot. The MYC-JA5D4X has integrated the SAMA5D4 processor, 512MB DDR2, 512MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY on board. They are served as the core controller of the MYD-JA5D4X development board and connected to the base board through DDR2 SO-DIMM 200-pin connector. They can also be embedded into your products directly which can speed up your time to market.

More FAQ >>


1. Do you use a standard interface for the ISI? Is there a camera board available for it?

Question:
Do you use a standard interface for the ISI? Is there a camera board available for it?

Answer:
The ISI is a standard interface but we have not made any software driver. We do not have camera module for the board at present.

2. What's the version of QT integrated in rootfs-qt?

Question:
What's the version of QT integrated in rootfs-qt?

Answer:
The QT version is 5.4.1.

3. Does the SPI Flash must be removed to use the ISI interface?

Question:
I find that the pinout PDF of MYD-JA5D4X Development Board says that the SPI Flash is connected to some of the ISI Camera interface pins. Does this mean that the SPI Flash must be removed to use the ISI interface?

Answer:
Our CPU module SPI flash is using PC0, PC1 and PC3 pins which are corresponding to the ISI signal lines D8, D9, D10 and D11. If the camera using 8 data lines, there is no conflict; If using 12 data lines, the ISI signal lines are needed to be reused and SPI code will be disabled, the CPU module hardware needs to disconnect the SPI flash jumper.
