Lolo and Bolo can't be restored. 1578 2
Started by hiroki
Hi everyone,
I'm trying to restore the lolo and bolo on my sdk-lh79520 board with reffering the LogicPD's Application Note 248.
But the restore sequence failed after I hit 'Ctrl-C' on the gdb prompt.
The following message has displayed at that time:
Attempt to force processor to enter debug state failed - excution
continues.
Could you help me

When I read back the registers value, I also see that bit 1 is sometimes set (no documentation I've seen refers to this bit as being of any use)...
I've only been able to download logics P/N: 70000015 I/O controller spec sheet (next to useless), and would like to know where I can get my hands on some detailed timing data, bit d...

LCD - LQ64D343 (sharp) does now work. 1577 2
Started by Deleted User
Hi,
I have taken the starter kit and after putting all things togather losh comes up and works fine.
I have LQ64D343 LCD separate and have made the LCD cable according to specs. Upon connecting all things and doing 'video-open 5 16' on losh prompt does not work. It gives time out and LCD remains as it is with some random vertical lines.
Any inputs
Is this proper way to test ( Logic ) or we can't use separate LCD and our data cable
I will appreciate any input on this..
thanks
bye

newer arm-linux-gcc crosscompiler toolchain possible? 1622 3
Started by JadePhoenix
Greetings!
I just want to know if someone successfully used a newer arm-linux-gcc cross toolchain either prebuild or self-made.
The one supplied with the BDK is rather old (2.95.x) and is not suited for our application development needs (C, templates) .
Is upgrading to newer toolchain (3.4.x with glibc 2.2x, libstdc v3) for this platform possible without much work/sidefalls
Did someone use cross toolchain build scripts like 'crosstool' for this purpose
Thanks in advance.
Best regards.

Lolo and Threadx 1623 1
Started by jmcclin2
Hi, I want to run Threadx app on the evaluation board in SDRAM; how can encapsulate the interrupts and exceptions for ThreadX if Lolo is down at location 0 where my interrupt/exception table should be (Or am I missing something here). All of the low-level threadX code that I have seen requires you to 'route' the interrupts and exceptions through Threadx so that it can save/restore the context properly.
Any insight would be great, thanks,
Jeremy

Possible Documentation Error 1659 3
Started by Anonymous
The PeriphClkCtrl register in the RCPC is documented in the Sharp literature as:
b3 : (reserved)
b4 : 0=Enable timer 0 & 1 clock. 1=disable.
b5 : 0=Enable timer 2 & 3 clock. 1=disable.
b6 : (reserved)
But, in the include file src/inc/sharp/LH79520_rcpc.h, we see...
define RCPC_CLKCTRL_CT0_DISABLE _BIT(3)
define RCPC_CLKCTRL_CT1_DISABLE _BIT(4)
define RCPC_CLKCTRL_CT2_DISABLE _BIT(5)
define RCPC_CLKCTRL_CT3_DISABLE _BIT(6)
Who's right

BoLo wont flash LoLo 1684 2
Started by Anonymous
I have overwritten LoLo with our application code to make sure it starts correctly on a reset. It does, so I then tried to use BoLo to re-flash the LoLo back in. The LoLo ELF image loads OK, but the burn command reports
unable to open /dev/flash11 for burn
Typeing 'burn /dev/flash11' gives the same result.
How can I reflash LoLo into the card engine
Many thanks.
P.S. Are these support questions actually monitored or acted upon

CF Reader/Writer for RedHat8.0 - getting file system onto 1523 2
Started by mpinton
I want to copy the file system generated by the build process to a CompactFlash card (yes, type 1) but haven't bought a reader/writer. Does anyone have suggestions for CF reader/writers that are known to work with RH I figure via USB. Can I just use any USB-based CF r/w Any other way to get the file system onto the CF card (anyway to do it from a Windows PC for instance)
Thanks.
