Title: Suspend Mode current - IMX233 Revisited in 2025!
Post by: srungerson on July 28, 2025, 04:14:22 PM
Hi,

I have to restore a legacy IMX233 platform and have re-imaged a WinCE 6.0 board SD Boot to Linux version 2.6.35 and EVERYTHING seems to work!

I have 2 questions in case anyone remembers all this!

Question 1>
Power in sleep mode under WinCE was just 15-20mw (4ma), but under Linux I go from normal power (~80ma) to just 60ma, not the 4ma I see in WinCE.

Should I expect the same 4ma Sleep mode from Linux as in WinCE? I can't find any specs :(

Question 2.
I understand there is a build 3.7.1 (https://github.com/koliqi/imx23-olinuxino) Does anyone have any experience in this or know where to find a .ISO or .IMG? Would anyone be willing to consult (or just help us) with advise on this IMX233 hardware update?

Thank you in advance!
SR

I've never done this before, and I have no idea where to go for a.ISO or.IMG file. Who can provide an answer?

You don't need img or ISO, there is a raw file in the GitHub OP linked and there are instructions on how to download it to SD card:

QuoteTo install bootstream onto SD/MMC card, type: sudo dd if=sd_mmc_bootstream.raw of=/dev/sdXY

where X is the correct letter for your sd or mmc device (to check, do a ls /dev/sd*) and Y is  the partition number for the bootstream

In my system sd device is /dev/sdb1, so writing bootstream file in card is done by:

$: sudo dd if=sd_mmc_bootstream.raw of=/dev/sdb1

Card is ready.
