Hello,
I checkout the prom/loader AND prom/loader-crc part and merged it
(perhaps I use git wrong way)
When I run the loader with "osmcon -m c123xor" the loader starts but
says "Failed to initialize flash".
I tried to "romload" it with "-m romload" there only beacons but no
valid response from phone.
Sending beacon...
Sending beacon...
got 1 bytes from modem, data looks like: ff
got 1 bytes from modem, data looks like: 00

1. Why the flash initialization fails?
2. Is it (currently) possible to run programs (ex. L1test from
flash)?
I (think I)read all this rom/ram/bootloader stuff.

The goal is to simple measure gsm rssi values of several channels very quickly.
Therefore I need a independent solution that not has to be "ramloaded" every
time when booting.

Hi Marco,
what is your goal, or better which guide did you follow? What was your

Additional,
I merged the shared directory to from "loader-crc" in "loader" branch
because it was not able to successful compile the newer "loader" branch.

Hi,
well, at first: the "-m romload"-switch is only intended for phones
which use the TI Romloader (which the Compal phones don't, and is called
"Romloader" because its stored in the maskrom of the Calypso).

This is basically the right approach, but the support for running
applications from flash is still under development. Ingo had it already
working as far as I know, but it still needs some work to be usable for
the public.
Did you use the flash unlock command first, before trying to write to it?

The message is shown at start of osmoload.
it looks like the "cfi_algo enumeration" makes trouble at line 518 in
cfi-flash.c
if(qry.p_id != CFI_ALGO_INTEL_3) {
/* we only support algo 3 */
return -ENOTSUP;
}
I am not sure but I commented out everything in flash_init() function and finally remove
the comments again one after another.
At line 518 the result is'nt 0 anymore.
Is that flash not supported?
It is hard to debug further because no printf() or puts() are possible in cfi-flash.c
Regards,
Marco

Hi Marco,

The calypso always supports booting from rom _BUT_ the nIBOOT pin determines
whether it boots from external NOR flash or from internal mask-rom.
Since that pin is hard-wired on the circuit board, you will only be able to
activate the calypso romloader on our supported motorola/compal phones if you
unsolder the Calypso BGA package, do some re-work and re-solder it ;)
Generally speaking: As far as I know, only prom (the original author) has been
using/testing the flash support so far. Only he would be able to know what
is supposed to work right now and what isn't.
