When I have the time I will do. It's a long time ago I made the calculation for 
the S3C2440 SoC...must read the datasheets again first.

DM9000 Timings.


  In the barebox code I see the value being set for the BANKCON4
register is 0x1F4C for the DM9000 chip. I am not sure whether this is
right. Trying to derive the values looking at the data sheet I get

Tacs -> 0 clock. (Should it be 1 clock or 10 ns?)
Tcos -> 1 clock. (10 ns). DM9000 datasheet I find it is T1 = 5ns.
Tacc -> 4 clocks (40 ns). DM9000 datasheet I find it is T2 = 22ns but
if nWait is present Tacc >= 4 clocks according to S3C2440 data sheet.
Tcoh -> 1 clock (10 ns).  DM9000 datasheet I find it is T5 = 5ns.
Tcah -> 0 ns (Should it be 1 clock or 10 ns?)
Tacp -> 00
PMC -> 00 (normal).

Could somebody please verify if this is correct?

Thanks in advance.

Understanding memory banks.


 I am confused with the memory banks of the S3C2440. Should I enable
only 1 memory bank? Also if the address/data lines are multiplexed
which chip should respond?

Error with libaprutil-0.so


I'm trying to build Apache for the mini2440 but I'm getting the following
error in one of its dependencies:

undefined reference to `crypt_r'

Looking online, it seems the fix is to link libaprutil-0.so to libcrypt.
What modifications are needed to be able to do that?

My configuration:
ptxdist - ptxdist-2015.01.0
toolchain - OSELAS.Toolchain-2014.12.0
bsp - OSELAS.BSP-Pengutronix-Mini2440 2015.01.0
apr-util - apr-util-0.9.19
apache - httpd-2.0.64

On Ethernet DM9000 data space in mini2440.


 I am trying to understand what is the address of LDATA0 - LDATA15
lines? Going through the busybox code I see it from S3C_CS4_BASE which
is 0x20000000. Where is this information present in the data sheet
that the LDATA0-LDATA15 lines are from that base address?

FFMPEG support on ptxdist 2013.03.0

Hi All,

I would like to enable the FFMPEG on BSP. I checked ptxdist 2013.03.0 ffmpeg.in rule file it is stated that
this package belongs to application section. When I checked the application section on menuconfig, it is
not showing up the ffmpeg there. I tried to copy the ffmpeg.in and ffmpeg.make to BSP rule but still it wont
show up in application section on menuconfig.

any idea how to bring in this ffmpeg package to the BSP without upgrading the ptxdist 2013.03.0?

Thank you in advance.

enabling BSP as full development environment

Hello Experts,

Is it possible we can enable the configuration of  BSP into a full development environment (enabling gcc
and linker)? Where you can do ./configure, make and install.

Has anyone done any work with the 10.1 inch display?  (Model W101)

Using the time honored tradition of 'stare and compare'; examining the 
datasheets for the 7 inch display and the 10.1 inch display, the

low entropy issue

Hi All Expert,

For the past few weeks, I never encountered depletion of entropy until yesterday where I could not able to
access my cortex A8 development board through wireless because of not enough entropy.

Searching for possible solution, I encountered rng-tool and haveged tool that possible to increase
entropy. I tried to find the rng-tool package from ptxdist menu but I could not find it. Somebody has idea
where I could enable it in the ptxdist menu?

Thank you!
