GT-I9023 hardware(chips)

---

Hi all,
I had made a decision to port u-boot for GT-I9023 few days ago, so I collected some chips info in this phone:
thanks AdamOutler and Rebellos for CPU

CPU: Samsung S5PC110
Baseband processor: Infineon 8824 XG616 X-Gold
Tx Front-End: Skyworks SKY77529
LCD: SONY NT35580
Touchscreen: Atmel MXT224
PMIC: Maxim Semiconductor MAX8998/National LP3974 PMIC ?
Audio: Woifson Microelectronics WM8994
MCP: Samsung KB100D00WM-A453(include 3Gb Mobile DDR, 1Gb OneDRAM and 8Gb OneNAND)
NAND: SanDisk SDIN4C2
BT/Wifi: Broadcom BCM4329GKUBG
NFC: NXP PN544
USB Switch: FSA9480
Touch keypad: Cypress ?
Compass: AK8973 ?
acceleration sensor: KR3DM ?
Gyro sensor: STMicroelectronics K3G
Ambient light and proximity: GP2A ?

Maybe there are something wrong in the list, please correct me.

From what ive read S5PC110 is what the galaxys series has. The S5PC110A01 is the rebranded and slightly tweaked Apple A4 processor

Let me know if you have a thread for this development, if not, pm me with your progress. I'm porting u-boot to SGH-T959V, and am planning to port it to other Galaxy S devices. https://github.com/bhundven/u-boot_galaxys/wiki

Well, here's point of mine and Adam eternal disagreement - I think S5PC110A01 = S5PC110 = S5PC111 = S5PC11<whatf***everIsHere>, and Apple A4 is something different. It's really hard to get out of that desinformative mess provided by Samsung documentation and various "Teardown Experts".
Enough to said that S5PC110 isn't CPU but it's PoP package, containing S5PC110 CPU and corresponding memory package with oneDRAM, LPDDR and oneNAND inside, CPU itself is under memory chip, so "chip id" in teardowns is usually taken from memory package writing, as CPU itself doesn't have any text on it.

I'd recommend you just grabbing Odroid's (the one with Hummingbird) Uboot, and it contain set of drivers for most of hardware you need. Just add some drivers from NexusS kernel sources. :P

We disagreed at one point that S5PC110 and A4 would not work the same.. I agree at this point. However, S5PC110A01 is the model number for the A4 processor. See here:Samsung-Intrinsity Apple A4 (S5PC110A01) RISC SoC

Can we change the internal ram of android device?

No, the cpu is under the internal memory (ddr and onenand) on the chip in a Package on Package configuration.

If there is any thing you could do (if you had the specs for both the internal memory, the cpu, and an ocilloscope) is try to optimize timings to gain tiny or maybe bigger (never know) in performance.

You would make those changes in the bootloader.

if by internal memory you mean internal storage (onenand), why not just modify the bootloader to boot a rom or linux distro from a partitioned usb device? rapid rom development.
