I am using the 10M16SAE144 with dual compressed images, but regadless of the state of the CONFIG_SEL pin, config is done all the time from CFM1. Both images are valid. I had changed the images vice versa, but configuration is always done from CFM1.
Internal Configuration, enable CONFIG_SEL Pin
not checked configure device from CFM0 only
not checked use second- image ISP as default setting if av.
Contents of the .map file:
BLOCK START ADDRESS END ADDRESS
ICB 0x00000000 0x00000FFF
UFM 0x00001000 0x00008FFF
CFM0 0x0004B000 0x0008CFFF (0x0006D643)
CFM1 0x00009000 0x0004AFFF (0x0002B82F)
Max 10 Setting:
Verify protect: OFF
Watchdog value: Not activated
Configure device from CFM0 only: OFF
POR: Instant ON
IO Pullup: ON
SPI IO Pullup: ON
I wonder at the fact that the addr of CFM1 is lower than the addr of CFM0.
Any idea what is going wrong?
Thanks for your answer.
I use the HW-pin of the device with a jumper (with 10k pull down resistor / 1k pull up resistor). The logic level change is ok (0.1V / 3.0V). Already changed the device, it is the same.
1) using the software method can not be done fast, because there is no processor inside the design and therefore I had to write some HDL code for using the avalon bus of the dual config ip.
2) I have made the measurement. Yes, there is a problem, because the value of the pull-down resistor (as stated in the document) of 10k is to large, 2k2 or less should be used. Changing this, shows a voltage level of 0.4V or less during power on.
But unfortunately this will not change the behaviour always booting the CFM1.
3) I have created two different .sof files with diff. names. Both are valid and when written in the CFM1 they work correct.
4) In the pin-out file one can see:
~ALTERA_CONFIG_SEL~ / RESERVED_INPUT : 126 : input : 3.3-V LVCMOS : : 8 : N
which show to me that the Config-sel-pin is an input.
Remember that there is only a passive 2k2 resistor to ground connected to this pin.
Why I can see a 20us low puls aprox. 10ms after PON, and why the pin goes to 0V aprox. 20ms after PON?
Can this be a reason for the problem?
Thanks for help.
