Topic: Bootloader/Image for a DLink DWL-2100AP

The content of this topic has been archived between 26 Mar 2018 and 5 May 2018. Unfortunately there are posts – most likely complete pages – missing.

This device have extremely low RAM. I use lightweight BB image with telnet and hostapd only, without luci and even dropbear.
Remember to shutdown wifi (hostapd) during sysupgrade.

hmm, i run "top" to see what take resources.
big problems with CPU - sometimes luci and dropbear take 99% but sometimes system takes 46%
Seems CPU  is very slow too.
Another problem.
When i first flashed router wifi was switched off and wifi led doesn't shined. I tried enable wifi but router stuck and I hard reseted him. Now led shine constantly. I tried disable, reset to default config and flash - shine...

Only power led (called "wlan") supported for default openwrt firmware.
CPU is ok, but memory very small and router runs out of it.

in my case:
power led - shine constantly
lan led - show ethernet status
wlan - shines constantly in a few seconds after switching on

Well, you can run "wifi down" and led will light again smile

Yes it's true smile

I get a similar bug at the stock image

kernel(1 114 112) + rootfs(2 490 368) + bootloader(167 464) = 3 771 944
flash is 32Mbit = 4Mbyte

Seems latest release  works only if recompiling without few packages...

I running custom minimal firmware with telnet and wpad-full only (dropbear and luci in flash, but disabled).
No problems more than week on 20+ devices.

_DS_, do you use  images from ftp or your own? If not from ftp what do you remove?
I checked md5 and and they matched.

I remove almost all except base system, wpad and telnet, because I need only wpa-enterprise ap's, nothing more.

Hi!
I have successfully runned openwrt on DWL-3260AP
because it have very similar hardware to DWL-2100 i share my result there.

ftp://linvinus.ru/openwrt/DWL-3260AP_op … R_14.07.7z

archive contains:
1)redboot image for DWL-3260AP and for DWL-2100AP that support following ROM chips
EN29LV320AB-70TCP , AM29LV320DBTI, AT49BV322A-70TU
2)redboot patches and sources that was used to build images.
3) openwrt image for DWL-3260 (it also may be used for DLW-2100, but because DWL-2100 have less memory you must disable snmpd after install before enable wifi)
4) openwrt config
5) instruction how to install openwrt on DWL-3260


I successfully installed OpenWRT on six DWL-3260 and two DWL-2100.

can some one explain what is contained in boardconfig ("/dev/mtdblock6"),
i know it contain mac addresses of nic and wan (at first 128 bytes)
but at offset of 0x10000 it contains something that looks like wifi firmware "RA.htresoC mouminac"
what is strange for me that if that data is broken redboot will not run at all.

bitbucket, you have done a good work.

.............................................

hi ramponis,

please clarify to me, what version of redboot in your site is the rigth one for the S29GL032M chip in DWL2100 A4 ??
( I guess the redboot220_mx.bin and the redboot220_mx.img files, but i'm not 100% sure) ???

Also, please clarify if the redboot(lzma).bin file is good for this chip (S29GL032M).
If yes (is OK for this chip), then the redboot(lzma).bin "replaces"  the redboot220_mx.bin file (and the redboot220_mx.img remains?) ?

Thanks for your time and best regards,
Jannis

Dear Ramponis,
thanks for the fast answer!

I read the mentioned WiKi link, but I could not find an answer on the specific issues I asked for (primary concerning the corresponding content in your site). Also my question for the use/compatibility of the redboot(lzma).bin file within the S29GL032M chip is not covered there.

Best regards
Jannis

You must read the page with more attention.
It is in the wiki, but i send you the direct link:

You have to follow the section "Bootloader replacement"
