ZBrain-System (Z48-C1, Z27-C1) features a standard connector for programming.
This connector features JTAG, FDM-UART and SPI-Bootlines.
A small ProgDongle (38x16mm) interfaces this connector to the JTAG emulator or to an RS232 PC port.
The ProgDongle serves several different functions:
- DSUB9 RS232 adapter cable for FDM programming
- order ProgDongle_STD for Z48-C1, Z27-C1 and custom hardware
- order ProgDongle_ZMC for ZMC
- If using FDM or JTAG, make sure the “boot” jumper is NOT set.
- The Flash Size is 64Mbit which is the size of the on board flash of Z27-C1 and half the size of the on board flash of ZMC and Z48-C1.
BootJumper Settings for ProgDongle_STD:
0E resistor, size 0603
The boot jumper determines which memory the processor boots from:
Not Set = boot from target memory (=normal boot mode)
Set = boot from ProgDongle memory
R3 Settings for ProgDongle_ZMC:
1k resistor, size 0603
The resistor R3 determines which memory the processor boots from:
R3 = not assembled = boot from target memory (=normal boot mode)
R3 = 1kOhm = boot from ProgDongle memory
