Does EDMA interrupt project "pcieboot_interrupt" support local reset?

Robert William

Hi,

For C6678 EVM with MCSDK (/mcsdk_2_01_02_06), helloWorld example project can run (ins/rm module) repeatedly with local reset (=1) defined. But the project "pcieboot_interrupt" cannot unloading/reloading.

After inserting this module, it is found in loading state with "cat /proc/modules" command.

"irqpoll" has been added to file: /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"

Can your project "pcieboot_interrupt" reload again?

Here is some further information.

The rmmod command cannot finish. It says the module is in use. Do you experience this error?

$ sudo insmod pcieIntr.ko
[sudo] password for r4: 
r4@r4-MS:~/ti/mcsdk_2_01_02_06/tools/boot_loader/examples/pcie/linux_host_loader/LE_interupt$ sudo rmmod pcieIntr.ko
ERROR: Module pcieIntr is in use
r4@r4-MS:~/ti/mcsdk_2_01_02_06/tools/boot_loader/examples/pcie/linux_host_loader/LE_interupt$

Hi,

Have you followed the “\ti\mcsdk_x_xx_xx_xx\tools\boot_loader\examples\pcie\docs\Readme.pdf” step to run the PCIe_boot example?

DSP reset command is not properly working on old version C6678 EVM, the issue is fixed on latest EVM revisions(Rev.3B). Provide your EVM Revision detail? Also share the entire test log on host PC, including lspci log.

Take a look at PCI Express (PCIe) Resource Wiki for Keystone Devices:

On the packaging, it has:

(2P) REV: 2A

Excuse me. I cannot access the host computer now for the log info.
