<wpwrak> hmm, i think the mantle (née maemo) guys should add an entry to wikipedia. now that AMD are using "mantle" as well, there'll be a heck of a confusion

<apelete> morning everyone
<apelete> larsc mth: just found out why the musb core couldn't discover the udc config by reading from hw
<apelete> it seems there is a register called configdata that usually holds usb config data, but it does not exists in the jz4740
<apelete> that means there is no way to autodetect config data nor endpoints...
<apelete> I'm angry with myself for having wasted some much time on this :-(
<apelete> so, next step would be to find out how to trick musb core into calling ep_config_from_table() instead of ep_config_from_hw() to setup endpoints

<DocScrutinizer05> wpwrak: fremantle
<DocScrutinizer05> apelete: :EEEEK:
<DocScrutinizer05> apelete: this all sounds so terribly similar to H-E-N hostmode
<DocScrutinizer05> apelete: temporarily we had a patch that allowed us to step maually thru every possible state of musbcore state machine, by sending commands to err /sys/musb/state or whatever (I forgot the name of sysnode, or was it even in /proc ?)
xiangfu has joined #qi-hardware
<apelete> DocScrutinizer05: let's hope the rest of the udc core in jz4740 is more "usb spec compliant"
<apelete> there seems to be some sort of support for devices that does not hold config data in the hardware, but I don't know how well it's going to work with jz4740
<apelete> s/support/support in the kernel/
<qi-bot> apelete meant: "there seems to be some sort of support in the kernel for devices that does not hold config data in the hardware, but I don't know how well it's going to work with jz4740"
<kyak> viric: why you're making it so hard to package? :) The download URL is http://vicerveza.homeunix.net/~viric/cgi-bin/filegive/tarball/filegive-0.7.1.tar.gz?uuid=v0.7, that means i need to hardcode 0.7 or use two separate variables
<kyak> viric: also, do you publish gpg key or md5sum somewhere? Just to be sure i downloaded what you actually packaged

<apelete> relying on ep_config_from_table() does not make it any better -> http://paste.debian.net/65724/:

<wpwrak> how about using pastebins ? :)

<apelete> wpwrak: just did above, but thought pasting the relevant part would help, sorry about that :-)

<apelete> anyway, the -EMSGSIZE return code is from fifo_setup() in musb_core.c, it seems ram address size is not read from raminfo register here...
<apelete> this is getting tedious, going to give up for tonight :-)

<wpwrak> don't you have a working driver you can use for comparison ? that's normally the quickest way to figure out where the problems are
