Custom Query (93 matches)

Hello, I have a problem when initiating a DMA transfer. I attached the platform (top.cpp, segmentation.h, platform_desc) and the application (MJPEG.x)

Everything runs smoothly, until a DMA transfer is initiated: [fetch_process] Send SOF info to LIBU and IDCT DMA transfer from 0x1004e620 to 0x1005779c (8 bytes)

I verified in vci_dma.cpp 134 VciInitSimpleReadReq<vci_param> *req = 135 new VciInitSimpleReadReq<vci_param>( 136 &m_data[0], m_src+m_offset, burst ); The correct src address is used, but on te next transition, a segmentation fault appears

Program received signal SIGSEGV, Segmentation fault. [Switching to Thread -1210737792 (LWP 5494)] soclib::caba::VciVgmn<soclib::caba::VciParams<4, 6, 32, 1, 1, 1, 8, 1, 1, 1> >::genMoore (this=0xbf948fb8)

at /tima/amazone-home1/chagoyag/Workspace/soclib/soclib/module/network_component/vci_vgmn/caba/source/src/vci_vgmn.cpp:380

380 can_take |= !m_dest->full();

I use compiler gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

Thank you for your help Alexandre

Bonjour,

Je tente actuellement d'installer SoClib (révision 5) sous environnement Windows. Pour cela, j'utilise l'API cygwin afin de disposer des outils de batch binutils.

• L'installation de SystemC pour cette cible est documentée : ​http://organact.mine.nu/dokuwiki/doku.php?id=astuces:cygwinsystemc. J'ai obtenu une compilation correcte ainsi :

1. configure
2. make pthreads (pas d'édition de la constante SC_DEFAULT_STACK_SIZE
3. make install
4. -> Commentaire des deux lignes wctomb et wcstombs dans systemc.h
5. make pthreads_check.

• L'installation de SoClib en suivant la page wiki donne les résultats suivants :

1. les utilitaires posent problèmes (fb en particulier en raison de la bibliothèque externe SDL)
2. la compilation de la plateforme d'exemple timer_4mips pose problème. La commande en cause est relative à la cible de compilation simulation.x

Les messages d'erreurs suivent.

Merci pour votre aide

Christophe

I had a soclib-cc error when i try to compile the caba-mjpeg-without-coprocessors

Error specializing caba:-0x7c4e9665, error:

NoSuchComponent "caba:vci_xcache"

I do not understand the error so i attached the soclib-cc debug log
