JMY980
JMY980 is a core board, 6 layer board design, and
the use of same long wiring to meet signal integrity. It contains the basic 5V power supply
power circuit, JATG the debug port, the user debug indicator, reset circuit, as well as the
core of the CPU and the memory cell. FLASH memory cell contains the NAND Flash and NORFlash
two types, selectable via jumper J1 NAND or NOR boot the system. NOR Flash which put the
BIOS does not change often, NAND Flash programming complete system program (Bootloader,
kernel, file system, etc.).
