KF 12:21 AM Software Development: RE: FS Corruption due to dropping power: Hi Mike,
Thanks for the reply. This is reasuring that it is a FS corruption problem. I have instigated a read only file system, based on your notes, and its seems to work, as in everything is mounted read only, and the application st... Keith Fletcher

MW 12:57 PM Software Development: RE: Starterware EMIFA to FPGA example code: Hi Emmett,
Are you using linux or starterware? On starterware, if you are launching from u-Boot (which configures the EMIFA to have some nominal timings for CS5 space), then all you need to do is perform memory read or writes to 0x66... Michael Williamson
EB 12:37 PM Software Development: Starterware EMIFA to FPGA example code: Hello,
I have used your "EMIFA_iface" VHDL example to make a simple FPGA to test by reading/writing to registers routed to the expansion I/O on the base board.
I need example C code to make the EMIFA transfers.
In the Starterware, I... Emmett Bradford

MW 06:31 PM PCB Development: RE: RTC Battery Drain: Hi,
Wanted to follow up on this. We have seen RTC battery drainage, but at the time we looked at it we were using Revision A silicon OMAP-L138 parts, which had some errata about power leakage that was fixed in the Revision B (standar... Michael Williamson
MW 06:28 PM Software Development: RE: FS Corruption due to dropping power: Hi Keith,
I have seen these symptoms before, and I'm pretty sure it's filesystem corruption related (I suspect udev related, not installing the /dev/ttyS* files due to a corrupted cached tarball of /dev which is by default stored off ... Michael Williamson

KF 04:29 PM Software Development: FS Corruption due to dropping power: Hi, We are developing a system where the user is unlikely to power down gracefully, even if asked to do so and ultimately intend to use a read only file system. However in testing we have not done this and have been dropping power to swi... Keith Fletcher

MW 09:46 PM PCB Development: RE: SODIMM Pin 53 ...: SPI1_SCS0 is indeed connected to that pin on the module. It is also connected to the chip-select on the on-board SPI NOR FLASH, which is used for loading the first stage bootloader (UBL) as well as u-Boot. The pin was brought out to th... Michael Williamson
TC 09:33 PM PCB Development: SODIMM Pin 53 ...: (Posted on behalf of a customer)
The datasheet for the MITYDSP-L138F shows Pin 53 as reserved, however the Industrial IO board uses it for SPI1_SCS0. Why does the datasheet show it as reserved?

MW 07:40 AM Software Development: RE: StarterWare question ...: Quick note. The new u-Boot command to load up the Starterware image was "bootelf" not "loadelf". I've corrected the wiki page. Sorry for the confusion (I was trying to post that before having to climb on an airplane!). The u-Boot im... Michael Williamson

SP 02:56 AM Software Development: RE: StarterWare question ...: see [[StarterWare]] Stéphane Peter

MW 02:33 PM Software Development: RE: StarterWare question ...: Hi guys,
Just wanted to give you a heads up that we've been able to get the EVM UART echo example in the TI startware up and running here at Critical Link. We've been able to load with with the debugger/emulator as well as load the E... Michael Williamson

SP 09:19 AM Software Development: RE: Dead board: All clear.
Today, I received a second Base Board - And with this new hardware, the CPU Board runs normally. --> So, a hardware defect on the Base Board is causing our problems.
Thanks for your time and help.
Best regards
Stépha... Stéphane Peter
JH 06:11 AM Software Development: RE: Write UART2 RS-485 API: Hi Mike:
Thanks for your response. It is working with the 2.6.34-rc1.
It is good timing to assert/de-assert TXE.
I am not sure that we need linux-v3.2 or not. I will try to patch it if we need.
Thanks,
Joe Joe Hung
