USB Mass Storage

Moin.

Since I have signed for the USB Mass Storage bounty, I started to toy with the USB manuals, AROS’ USB stack and Efika. During my coding evening it suddenly turned out, that I’ve lost the bits and pieces of AROS USB code which were responsible for Bulk transfers. Funny. They were there a very long time ago, among my sources, now they were gone.

Whatever. I’ve added the bulk transfer support to USB stack implemented it in both OHCI and UHCI driver (the support for UHCI will follow shortly) and wrote the first bits and pieces of mass storage class. Here’s the result:

YASU – Yet Another Status Update

Hello there,

There is actually not much to tell you, except the small status update :)

The development of AROS for Efika is an interesting coding experience. Some parts come without any trouble, and are ready to use, stable and usable just out of the box. Others require a bit more patience and documentation reading.

I have put a whole bunch of modules into the Efika kernel and they do seem to work properly. As I wrote the last entry in my blog, efika kernel consisted of 23 modules. Now, there are 40! All of them seem to work :-D. The PCI driver for MPC5200B successfully scans the PCI bus full of interesting devices

[PCI] Adding driver PCINative (Efika5200 native direct access PCI driver) to the system  
[PCI] Scanning bus 0

[PCIDevice] 00.1c.0 = 1057:5809 (Bridge Other )  
[PCI_Efika] All OK

The timer.device is ready and working. It uses slice timer which, at 33MHz timebase clock, has a minimal resolution of 7 microseconds. If it will be insufficient then I will try to change the clock used. Beloved dos.library complains that no bootable volumes have been found:

[DOS] __dosboot_IntBoot: Could not open bootmenu.resource, something’s wrong!  
[timer] OpenDevice(1)  
[DOS] __dosboot_IntBoot: Checking MountList for useable nodes:  
No bootable disk was found.  
Please insert a bootable disk in any drive.  
Retrying in 5 seconds…

The USB stack is working. It has found my USB stick, yet it is unsupported :))

[USBDevice::New] Address=02, Interface=00, Bus=0x899e4, Hub=0x899e4 
[USBDevice::New] Device 1d00:13fe 00/00/00 at address 000899e4:02

[USBDevice::New] iManufacturer = “Kingston”  
[USBDevice::New] iSerial = “5B72059F82DF”  
[USB] USBDevice::New() = 0x94804  

The Efikas MPC5200B CPU has built in OHCI USB controller. Yay! That was fun! Allthough all usual OHCI controllers work in little-endian mode (even the one in PPC based Sam440/Pegasos/AmigaOne and others!!). MPC5200B is different. Here, the whole OHCI chip is a big endian beast. Respect! And wasted time for me 😉

In order to complete the Efika bounty, I need to do

  • ata.device specific for MPC5200B. If I will do my best, DMA transfers will work.
  • Network driver for Efika. The rest of TCP/IP stack is already there.

But hey! How will you install AROS on harddrive then? Tftpboot? Hard to do. Remove harddrive and use another machine? Almost impossible and stupid. Well?…

There is a way. Allthough the Poseidon bounty is open, I cannot wait for this bounty. Instead, I will apply for the bounty number 25. What do you think about? Am I cruel? Evil? Will my work on USB mass storage be pointless in spite of Poseidon? Tell me what you think about – I’m ready for all kinds of criticism 😉

During next few days I will consider what has a higher priority right now: USB Mass Storage or ATA. 

Cheers :)
