Bassano del Grappa, Italy - 6 December 2010

ACube Systems is pleased to announce yet another new release of the U-Boot firmware for its line of motherboards Sam440ep and Sam440ep-flex.

What's new in this version:

* Fixed wrong setting for the MMUCR register
* Introduced a new Video Option: Console. Setting it to ?Silent? will produce a more nice looking boot screen (see picture below)
* On Sam440ep-flex: if a SiliconMotion 502 is present, and it's not set as primary video card, the SM502 I/O and MEM access are disabled in PCI_COMMAND register after initialization. This prevent some problems when booting AOS4.1 in a dual gfx card setup.
* On Sam440ep-mini: if a Radeon PCI card is present, and the onboard video card is not set as primary video card, the onboard video card I/O and MEM access are disabled in PCI_COMMAND register after initialization. This prevent some problems when booting AOS4.1 in a dual gfx card setup.
* Solved a problem when assigning IRQ to a video card behind a PCI to PCI Express bridge (RadeonHD)
* Video unit and Sprite unit are switched off on SM502
* Solved a problem with the Blitter unit registers not reset to default values at powerup on SM502
* Now it's possible to set baudrate to 230400 and 307200 bps (for faster debug output)
* Changed boot logo
* Reduced font size

The updated installation guide describes in detail the usual installation method (ISO image) and alternative methods (TFTP).

Not ACube's fault, but all the scrolling text needs removing (most of it is debugging stuff which should never have made it into a user release). A menu which looks similar to the Parthenope one would look much neater, with the necessary credits/version numbers printed at the bottom of the screen underneath the menu.

Quite a regular Joined: 11/19/2008 From: Tarsus IV Comments: 548	Re: U-Boot 1.3.1c for Sam440ep released @ Richi You have a strong point here. This is taken from the UBoot update: Quote: Fixed wrong setting for the MMUCR register ...and this one from Sam440_SetupTool: Quote: on some Sam440ep boards, the MMUCR register is not set correctly at bootstrap. This leads to poor write L1 cache performances. The utility check the register, and if needed, modify it. But probably fixes only the first part, that's why the setup tool is still needed.
