Re: FW 4 iPod Nano 3G clone
Sorry, I am not familiar with ACU75xx hardware. Possibly some other ports need to be set to enable CE function.
You can try downloading the ACU75xx firmware on s1fw.com, disassemble a BREC from one, then look at address 3000 for the code which displays hourglass. It will set the ports to select appropriate CE for the display. More information at http://wiki.s1mp3.org/ |
and for ak1025 you know this hardware?

Just a little issue: this is a firmware for a 220x176 px display, while my display has a 160x128 px resolution! :evil: :( Flashing the player with this firmware shows the hourglass in the upper-right portion of the display, then some "fluctuating pixel dust" because the CPU tries to display an higher resolution, and the display can't... but it works! :wink: After the flash I have dumped the firmware from the player, and this is the s1fwx's result: Code:
connect to device 'E:\'...Meanwhile, with the help of s1fwx, i have (unsuccessfully) tried to build a new firmware using the *.BIN files from this firmware and the FWIMAGE.FW file from your firmware, but the player loop on hourglass (translated: the firmware does not work...) Lolita, can you take a look to it for me? :roll: :oops: |
Re: FW 4 iPod Nano 3G clone
The BREC code in the working firmware you provided selects CE5 by the usual means. However, your mention of CE1 fluctuating when accessing the flash suggests that the appropriate CE is enabled *only* during read/write operation.
Select CE5 ("o 2 28" in s1giveio), then try reading anything from memory address 8000 or above (e.g. "r 8000") while monitoring CE5. It should pulse low and then go high very very quickly, once the read is complete. However, getting an hourglass means the controller code in the BREC is compatible with your player, but the one in the firmware you provided is for a "big PCF8833-compatible" type LCM controller; as you may remember, the original GXBL177-xxxx firmware you found is for a different controller, the rarer HD66xxx. Maybe that one was mislabeled or GXBL177 is actually the backlight's part number, and GA177 is the actual display's part#. This confirms that your player has the "big PCF8833-compatible" type controller, probably LDS285,ST7669, or ST7732/35/73. Firmware for those are much easier to find. Is the only issue with that firmware the incorrect screen size? I.e. controls, playing music, etc. works? s1fwx cannot work with v9 devices. Use s1res v4.0 instead. |

I will try with an oscilloscope... if I find it :) However, I've traced the CE line during the player's boot, and during the "pixel dust" it is fluctuating, so it seems that the CE5 line works correctly. Quote:

- Internal flash memory works - Additional MicroSD flash memory works (no SDHC support) - Keys works - MP3 playing works (the display shows - distorted - folder, track name and volume icon) I don't have tested the FM radio (but this is a minor problem). :roll: Quote:

This firmware is also for an LCM with the same controller type on CE5, and is also 128x160. The only problem is the connectivity is wrong -- the backlight is on E4 (you have it on A2), reset is A0 (same as yours), command/data A1 (yours is on B2). If you cannot find a 128x160 firmware with same LCM and connectivity, then we can edit the drivers in this one and change the connectivity so it matches your player, and probably will have to transplant your keyboard driver into here, since this one has a different keyboard connectivity as well. The following LCM will have a compatible controller, try the firmware for these: CGS172STBY-1V1 TGG000177NP02-02 TGG000177NP02-03 TGG000177NS02-03 TGG000177YP02-01 TGS177SH00 TGS177SH-ST TGS177STWT-3V1 TGS177STWT-4V1 TGS177STWT-5V2 XY-1.8A GA177 |
what is lcm for fgd177slw screen?

However it seems to be very rare, as the only firmware I could find with this LCM, and the one from which I got the controller type, is this: http://bbs.mydigit.cn/read.php?tid=89348 The firmware itself only uses 128x160 though. |
