Support : PROMJet Frequently Asked Questions
Please use this section to get answers to the most frequently asked questions about PROMJet FLASH emulator. If you do not find an answer to your question below, please do not hesitate to contact our support team.
Can the ICE options used with the GDB or Eclipse debugger interface?
PROMJet is fully integrated in DebugJet JTAG debug interface. PROMJet ICE option is also fully supported to read memory on the fly without stopping the CPU under test.
Can I use PROMJet to Program an on-board FLASH chip?
PROMJet is used to emulate the Flash memory chip. In most cases, the user needs to remove the Flash chip and insert PROMJet adapter to act in place of the Flash chip. If the user is designing a new board, it is recommended to contact EmuTec to get the pinout of the 50-pin header to implement on the board. This will provide a more sold connection and save the extra cost of a Flash adapter. The DebugJet product line does support the programming of a wide variety of Flash and FPGA/CPLD chips via the JTAG interface.
What SPI Flash functions are supported by PROMJet?
PROMJet supports the following SPI Flash functions: READ (Code 0x03), PROGRAM (Code: 0x02), FAST-READ (Code: 0x0B), JEDEC ID (Code: 0x9F), CHIP ID (Code: 0xAB)and READ STATUS REG (Code: 0x05).
Do I need an external adapter to support SPI Flash chips.
All the logic needed to translate the SPI signals is embedded inside PROMJet. The user will need a footprint adapter to go from our 50-pin header to an 8 or 16 pin adapter.
What LPC/FWH Flash functions are supported by PROMJet?
PROMJet supports the following LPC/FWH Flash functions: read, program and get manufacturer and device ID.
Do I need an external adapter to support LPC Flash chips.
All the logic needed to translate the LPC signals is embedded inside PROMJet. The user will need a footprint adapter to go from our 50-pin header to a 32-pin PLCC adapter or a 40-pin TSOP adapter.
Does PROMJet support LPC and/or FWH interface?
It supports both interfaces. PROMJet will monitor the LPC bus and respond to both LPC and FWH commands. No user selection is needed.
What functions are supported by PROMJet in 8/16 bit Flash mode?
PROMJet supports read and write functions when set in parallel 8/16 bit mode (non-serial mode as with SPI or LPC). It does not support the programming algorithm, as it does under SPI and LPC, used to program Flash memory. It can be viewed as a RAM rather then ROM or Flash memory.
