Re: Can MOD54417 Flexbus be used in 32-bit mode

Hi, I have recently experimented with a MOD54415 to communicate with an FPGA via a 32-bit and 8-bit bus. While there is an on-board latch, it is not exposed externally and is used just for interfacing with on-board flash. This latch should have no noticeable effect on the bus when interfacing with e...

Re: Can I use J-LINK Debugger with MODM7AE70 ?

The MODM7AE70 was not designed with the intention of using an external hardware debugger. Debugging features you would use an external debugger for can be done with the GDB network debugging tools... ie breakpoints, stepping through code, watching memmory or variables, ext. Is there some type of deb...

Re: MODM7AE70 external memory software example

Hi, NNDK 3.1 has an EBI example in it. ( ..\nburn\examples\PlatformSpecific\MODM7AE70\EBI_Paging ) The external bus buffer enable is missing from this example but has been added for the next release. Just include bsp.h and call EnableExtBusBuff(true) from UserMain in your initialization. The importa...

Re: MOD5234 High Z functionality not working

The J2[35] pin of the module is directly connected to the LTPUODIS or J14 pin of the MCU. This signal is not connected to any other circuitry on the NetBurner module. According to the MCF5234EC (electrical specifications manual): All pins which are configurable for GPIO have a pullup enabled in GPIO...

Re: Flashing a MOD5270 & MOD5270B

The platform is detected with the first line (S0) of the S19 file. For example, the MOD5270 .s19 first line should be: S0MOD5270. If you remove the S0 line from the .s19 file then AutoUpdate will not check the platform before updating. This will work for swapping between MOD5270 and MOD5270B modules...

Re: controlling the Uart DTR pins on a SB700EX

Hi,
Look at the header file for serial:
C:\nburn\include\serial.h

This contains functions for reading or setting on the various "extra" pins of the DB9:
BOOL GetCD( int port );
BOOL GetRI( int port );
BOOL GetDSR( int port );
void SetDTR( int port, BOOL val );

Re: MOD5213 QSPI PROBLEM

I have used QSPI in this fashion for high speed A/D reading. Usually the way this works is by first sending a 16-bit command to the sensor. After the sensor has this command it knows which data to send back. The next 16-bit transfer will contain the data returned from the previous command on the RX ...

Re: MOD5207 to Coldfire pin mapping

There is a header file used for this pins class that lists the processor pin number for any pin that can be multiplexed on the J1 or J2 headers:
C:\nburn\MOD5270\include\pinconstant.h

Re: MOD5207 to Coldfire pin mapping

You stated that you were looking to use the Ethernet Controller MDIO and MDC signals. Chapter 2 of the Freescale reference manual shows that those signals are only routed to the pins D5 and D4 of the processor. Both of these signals are routed from the CPU directly to the Ethernet PHY, specifically ...

Re: MOD5270 Internal Reset Circuitry

The MCF5270 has its own internal reset controller. The RSTI signal is routed to pin N13(reset in) of the processor, J1[28], and J3[7] (the BDM header). It also is connected to a 4.7K pull-up resistor. The RSTO signal comes from the processor pin P13 and goes to the Ethernet PHY, a boot configuration...
