P2 Edge Rev B, FlexProp 7.3.0 Program not saving to flash

Mickster

Been a while since I worked with this stuff but I remember that I could run a program, cycle the power and the program would still be there and would auto-start. Now it doesn't store to flash, or have I forgotten something?
The switches haven't changed (I have two of these modules).

Even when I select "Compile and flash" I get a message in the terminal:

ERROR: timeout waiting for checksum at end: got 1
Try increasing the FIFO setting if not large enough for your setup
Press enter to continue...

Can't find anything re: FIFO

Maybe I'm mistaken. Used an older version and the terminal gives me:

Invalid option -SPI
loadp2 - a loader for the propeller 2 - version 0.060 Sep 23 2023
usage: loadp2
[ -p port ] serial port
[ -b baud ] user baud rate (default is 115200)
[ -l baud ] loader baud rate (default is 2000000)
[ -f clkfreq ] clock frequency (default is 80000000)
[ -m clkmode ] clock mode in hex (default is ffffffff)
[ -s address ] starting address in hex (default is 0)
[ -t ] enter terminal mode after running the program
[ -T ] enter PST-compatible terminal mode
[ -v ] enable verbose mode
[ -k ] wait for user input before exit
[ -q ] quiet mode: also checks for exit sequence
[ -n ] no reset; skip any hardware reset
[ -9 dir ] serve 9p remote filesystem from dir
[ -FIFO bytes] modify serial FIFO size (default is 1024 byte
s)
[ -? ] display a usage message and exit
[ -DTR ] use DTR for reset (default)
[ -RTS ] use RTS for reset
[ -xDEBUG ] enter ROM debug monitor
[ -xTAQOZ ] enter ROM version of TAQOZ
[ -xTERM ] enter terminal, avoid reset
[ -CHIP ] set load mode for CHIP
[ -FPGA ] set load mode for FPGA
[ -PATCH ] patch in clock frequency and serial parms
[ -NOZERO ] do not clear memory before download (default)
[ -ZERO ] clear memory before download
[ -SINGLE ] set load mode for single stage
[ -NOEOF ] ignore EOF on input
filespec file to load
[ -e script ] send a sequence of characters after starting
P2
[ -a arg1 [arg2 ...] ] put arguments for program into memory

In -CHIP mode, filespec may optionally be multiple files with address
specifiers, such as:
@ADDR=file1,@ADDR=file2,@ADDR+file3
Here ADDR is a hex address at which to load the next file, followed by = or +
If it is followed by + then the size of the file is put in memory followed by
the file data. This feature is useful for loading data that a program wishes
to act on. For example, a VGA program which displays data from $1000 may be
loaded with:
@0=vgacode.bin,@1000=picture.bmp
The main executable code must always be specified first

Make sure the FLASH switch is ON-upward (and the two arrow switches OFF). -- if FLASH is already on, then toggle it on/off a couple times; might just be a lazy connection from sitting/bashing around.
Also ensure the SD card is removed (if you have one inserted

Still the same with both Rev B modules. I get the same message as in OP. The binary is only 7KB

Mickster

Just realized that the #2 module fired-up blinking an LED so clearly that program was successfully stored, many moons ago.

I’d try with prop tool or spin tools

Or -single

Or maybe add fake data so program is bigger…

Cheers, Ray.
Yeah I had the same idea re: prop tool. It doesn't complain when sending the binary but the progress indicator is done in the blink of an eye and the program doesn't execute. I don't believe spin tools directly handles binaries(???).
Ya know what, I'll get back to my desk and try some regular SPIN programs to see if any different

Mickster

Sure enough

Blink1.spin2 saves to flash and runs after a power cycle.

It does. Use F11 just like in Propeller Tool. Note that it does use its own loader.
