Frequently Asked Questions
General FAQs
- Can the PlanetCore loader be booted into a "quiet" mode, where it does not output characters to the monitor port when the Autoboot is enabled?
- The PlanetCore loader has several "quiet" mode options when booting. Refer to RS232 and SerOut EEPROM keys in the PlanetCore boot loader manual to understand each option and how they work together.
- Can the PlanetCore diagnostics be called from my program?
- The PlanetCore diagnostics were not designed to be called from an external program.
- How can I find out how to read the STTM?
-
The STTM is located on the I2C bus. You can access the data sheet for the part at http://www.telcom-semi.com/products/datasheets/tcn75.pdf. The I2C addressing information is available in the documentation for the board.
NOTE:If you need code examples for I2C, check the Motorola site.
- Where can I find information on the EEPROM?
-
The EEPROM is located on the I2C bus. You can access the data sheet for the part at http://www.atmel.com/atmel/acrobat/doc0180.pdf. The I2C addressing information is available in the documentation for the board.
NOTE: If you need code examples for I2C, check the Motorola site.
- How can I get schematics for the boards that I purchase?
- Our products are production intent, which means you can use them for application development, prototyping, and full scale production. The board documentation will give you information on how to use the expansion connectors and expansion bus of the board. The expansion bus gives access to CPU and I/O signals. This information should provide you with enough details to create a product using Embedded Planet boards. If this is not enough, you can purchase the schematics from our sales department.
- Can I write values to the EEPROM?
- You can write to the EEPROM in the area that is not reserved by PlanetCore. Refer to the PlanetCore manual for the reserved locations.
- What PCMCIA Assemblies are you using?
- Berg 95547-150CA, connector 91931-31169

- How do I program flash?
- The PlanetCore flash burner program is used to program the flash. With the PlanetCore flash burner you can load and burn your image either using the PlanetCore loader or debugger. The flash burner program is an executable program (executes on the target board) that reads data from RAM and programs to flash. No special hardware is required if the PlanetCore boot loader is resident on the board.
- How do I change my MAC address?
- You can use your own MAC addresses if your company has acquired them. Contact Embedded Planet support for instructions.
- What is the FEC MAC address?
-
Each CPU board has one or more media access control (MAC) addresses assigned to it. The MAC address is the physical address of a device connected to a network, expressed as a 48-bit hexadecimal number. The boards are assigned MAC addresses during manufacture using the following convention:
Enet controller 1 MAC = 0x0010ECxxxxxx ORed with 0x000000000000
Enet controller 2 MAC = 0x0010ECxxxxxx ORed with 0x000000800000
Enet controller 3 MAC = 0x0010ECxxxxxx ORed with 0x000000400000
Enet controller 4 MAC = 0x0010ECxxxxxx ORed with 0x000000C00000where xxxxxx is the EP board serial number. The serial number can be found in decimal form on a label affixed to the Ethernet port on
the board (e.g., 007573).For example, a board with a serial number of 007573 decimal (001D95 hexadecimal) has a MAC address of:
0010EC001D95 for Enet controller 1
0010EC801D95 for Enet controller 2
