Thanks Tom. Jonathan Cormier

FYI... have made the following changes to the recipes as to update fetching the proper sources. For vim it's a different URL and for ltrace it just needed a branch designation. Someone may find them useful. Tom

Hi, well it was easier then trying to fix the two repo failures, (which I will do)... just running bitbake again without the -k saw it succeed and now have the jffs image. Tom Tom Riddle

Could you provide a log of your bitbake command plus output in an attached file? Jonathan Cormier

Hi Folks... any feedback on where the image might be? Thanks, Tom Tom Riddle

AB 03:18 PM PCB Development: RE: OMAP L138 HPI

Unfortunately during my initial review of the modules with and without FPGA I confused the RESETOUT (T17) pin connection for the FPGA module.
As you have found T17 from the L138 is not connected to an FPGA IO but is connected to a ded... Alexander Block

Thank you.
I was able to check the connection information between FPGA and L138.
Could you tell me the pin wiring of ball T17(UHPI_HAS) of L138?
It seems necessary to connect to power supply(1.8V or 3.3V). Hisato Seki

You can find the pin-out between the FPGA and the OMAP-L138 processor of the module in the Carrier Board Design Guide (Table 4):

Thank you for your reply.
Sorry, I missed BALL R16, R17.
I found that a board with FPGA(MityDSP-L138F) is necessary.
Is there a way to know the connection information of L138 and the FPGA in the board(board schematic etc)? Hisato Seki

TR 04:37 PM Software Development: RE: Yocto MDK Status

Hi Bob, thanks for the quick response, I'll start playing with the recipe.
On the rootfs question, can't seem to find the file, see the dir listing below. Perhaps I need to build or execute something else? All I have done to date is

Thanks Jonathan I will give that a try, in the meantime there are a few other questions.
So we have a 3.2 kernel here with a moderate number of modifications that is based on the 2011 MDK kernel source. We can continue to build it sep... Tom Riddle

I'm not sure that we've used the UHPI interface in any designs nor am I aware of any customers that have utilized the UHPI.
Are you interested in the MityDSP-L138 with or without the FPGA?
* For the module without the FPGA the UHPI... Alexander Block

HS 08:32 AM PCB Development: OMAP L138 HPI

I am looking for a board that can use HPI function of DSP of OMAP L138.
Is it possible to operate HPI using MityDSP-L138 and another HPI host MPU?
