Visto che mi ha un po' rotto i maroni questa storia, provo a compilare gcc e gdb per architettura ARM e OpenOCD e vediamo se funziona con quello..

da **xyz** » 27 lug 2013, 18:56

Compila prima OpenOCD, gli altri software non contengono codice per comunicare a basso livello con USB. OpenOCD implementa un remote protocol server utilizzato da gdb per comunicare col dispositivo.

da **simo85** » 27 lug 2013, 19:02

OK. Questo vuol dire che posso eseguire OpenOCD per comunicare con la board anche senza aver compilato ed installato gdb giusto?

da **xyz** » 27 lug 2013, 20:15

OpenOCD se funziona e riesce a comunicare via JTAG con la board puoi mandare i comandi via telnet attraverso una comunicazione TCP/IP con l'indirizzo localhost e la porta 4444 (è quella di default, è possibile cambiarla) senza passare via gdb.

I comandi sono questi:

Grazie per il link

Stavo giusto navigando nella doc di OpenOCD e mi hai anticipato. :-)

Appena lo compilo e lo eseguo posto i risultati. [-o<

xyz ha scritto:Mi ricordo di aver letto dei problemi con alcune board che non rispettavano le specifiche USB e il kernel resettava la comunicazioni USB in caso d'errore.

Tra l'altro, dopo alcune ricerche sono arrivato a questa pagina:
http://capitanio.org/mlink/index.html

Nella quale l'autore riporta:

"The discovery’s stlink (both st8, st32) implementation of the USB protocol violates the USB standard in multiple ways and it's too much broken for the linux kernel driver. Although it's possible to intercept the core and write/read a data in some for that designated SRAM region, there isn't any direct communication channel to the chip over the USB. The right (but long term) solution will be to replace the stlink firmware."

Anche nel sorgente a questo link:
http://arm-utilities.googlecode.com/svn ... ink-test.c

si legge:

Codice: Seleziona tutto: static const char usage_msg[] = "\nUsage: %s /dev/sg0 ...\n\n" "Note: The stlink firmware violates the USB standard.\n" " If you plug-in the discovery's stlink, wait a several\n" " minutes to let the kernel driver swallow the broken device.\n" " Watch:\ntail -f /var/log/messages\n" " This command sequence can shorten the waiting time and fix some issues.\n" " Unplug the stlink and execute once as root:\n" "modprobe -r usb-storage && modprobe usb-storage quirks=483:3744:lrwsro\n" "\n";

Dall'ultimo messaggio si capisce lo strano comportamento con le varie versione del kernel. Lo stack USB del kernel di Linux ha aumentato i controlli di validità sul protocollo e le schede che violano lo specifiche di comunicazione non funzionano o funzionano parzialmente.

Oltre a complimentarsi con ST per il clamoroso baco, le soluzioni proposte sono quella di sostituire il firmware, se esiste una versione corretta o vengono proposti alcuni workaround parzialmente funzionanti.

da **simo85** » 28 lug 2013, 10:26

Già, pero rimane comunque da scoprire perché sul mio laptop e con la distro configurata da me non funziona e sul laptop del mio amico con la Ubuntu si. Saranno le versioni del kernel però non ho ancora avuto la possibilità di vederlo e di verificare il tutto assieme di persona. Forse in questi giorni.
Capisco i bug però questo fatto non lo capisco :-M

ho la testa dura e voglio capire il perché.

Ad ogni modo in giornata, probabilmente questa sera vedrò di compilare OpenOCD.
Speriamo che gli esiti siano positivi.

da **simo85** » 28 lug 2013, 17:19

Ciao

xyz, sono riuscito a compilare con successo openocd.

Da quello che ho capito bisogna configurarlo un file di configurazione con x.cfg con l'opzione -f.
Dunque i file di mio interesse penso dovrebbero essere questi o per lo meno uno di loro:

Codice: Seleziona tutto: ~ $ ls /usr/local/share/openocd/scripts/target/ | grep stm32f4 stm32f4x.cfg stm32f4x_stlink.cfg stm32f4xx.cfg

Ho cercato qualche riferimento al ST Link/V2

Codice: Seleziona tutto: /usr/local/share/openocd/scripts/target $ grep -r stlink-v stm32f4xx.cfg:source [find interface/stlink-v2.cfg]

Seguendo questa pagina al paragrafo 4.1, secondo quanto riportato ho eseguito

Codice: Seleziona tutto: $ openocd -f board/stm32f4discovery.cfg -f interface/stlink-v2.cfg Open On-Chip Debugger 0.7.0 (2013-07-28-16:43) Licensed under GNU GPL v2 For bug reports, read http://openocd.sourceforge.net/doc/doxygen/bugs.html Error: The specified debug interface was not found (hla) The following debug interfaces are available: 1: ft2232 Runtime Error: /usr/local/share/openocd/scripts/interface/stlink-v2.cfg:5: in procedure 'script' at file "embedded:startup.tcl", line 58 at file "/usr/local/share/openocd/scripts/board/stm32f4discovery.cfg", line 4 in procedure 'interface' called at file "/usr/local/share/openocd/scripts/interface/stlink-v2.cfg", line 5

Da quello che ho capito c'è un errore e non riconosce il dispositivo hla, settato e dichiarato in stlink-v2.cfg

Codice: Seleziona tutto: $ cat ../interface/stlink-v2.cfg # # STMicroelectronics ST-LINK/V2 in-circuit debugger/programmer # interface hla hla_layout stlink hla_device_desc "ST-LINK/V2" hla_vid_pid 0x0483 0x3748

Immagino bisogna sostiture il nome dell' interface dico bene? Se si, come? :roll:

È la prima volta che lo uso e sono cotto dal lavoro.. Timeout.

A parte di qualche aiutino a riguardo adesso ho bisogno di un

Codice: Seleziona tutto: # init 0

A presto e grazie ancora per l'aiuto che mi stai dando. :-)

Simo

Sembra che l'errore precedente era dovuto al fatto che non ho passato l'opzione --enable-ti-icdi in fase di compilazione di openocd. Dunque ho ricompilato.

Però.. Ora l'output è il seguente:

Sto cominciando a pensare che l'architettura x86 dia più problemi rispetto alla x86_64... :roll:

Se è così reinstallo e ricompilo tutto a 64 bit. :twisted:
