Hi I'm new to this list so I hope that this is the right place for my question.
I have a board with mpc5121e cpu on it and I'm been patching my Uboot (U-Boot v2009.11) with the patch given initially by Francesco Rendine: http://lists.denx.de/pipermail/u-boot/2009-June/055022.html It seems like that every time I run 'usb start' from the Uboot prompt it crashes the Uboot like: ------------ Hit any key to stop autoboot: 0 => usb start (Re)start USB... USB: U-Boot 2009.11.1-svn813 (Aug 16 2010 - 15:07:33) MPC512X CPU: MPC5121e rev. 3.0, Core e300c4 at 396 MHz, CSB at 198 MHz Board: V39 Revision B I2C: ready . . . ------------------- After some debugging it seems to be in the ehci_hcd_init(): - hcor = (struct ehci_hcor *)((uint32_t) hccr + HC_LENGTH(ehci_readl(&hccr->cr_capbase))); this line makes it crash. Regards Einar
