Let's learn ARM using cheap 7" tablets

[Macgyver]

paano niloload yung program (BIN file) to the APAD?

['yus]

^ 2 ways ang alam ko, both using the u-boot (bootloader)
sa ngayon, TFTP transfer ang ginagawa ko. the other is from SD card ilo-load.

ethernet transfer papuntang RAM ng board, and sa RAM lang din sya nagra-run kaya di mao-overwrite ang original OS.
1. use this free app para gawing tftp server ang host pc.
2. enter u-boot console (i.e. "WMT#" prompt)
3. send "tftp 100000 filename.bin" sa console -> transfer file from host pc  to RAM located at 0x100000
4. send "go 100000" -> execute command located at 0x10000

yung sa SD card naman,
gagawa ng script para iload yung bin file during bootup.

^nice.  para ka nang may arm dev board.  may LCD touchscreen pa

[maldihtah13]

^ usb-to-ttl lang sir, 3.3V logic..

Pwede na ba yung USB to TTL ng e-gizmo?

['yus]

^nice.  para ka nang may arm dev board.  may LCD touchscreen pa

thanks... yung touch screen naman next ko..

Pwede na ba yung USB to TTL ng e-gizmo?

di ko pa nate-test, pero malamang gagana yung PL2303 based nila..

[Kaizer03]

Update: hehe after a month, kanina ko lang ulet nabalikan..

nagpasabay kasi ako ng MAX3232 sa officemate ko kanina na dumaan ng gizmo ayun

dahil di ko mahanap yung Serial port pins sa loob ng android tablet, ang ginamit ko eh yung sa Adapter.. [see yus' 1st post about FREE additional Serial Port]

and ayun, nabasa ko yung data nya through hyperterminal...



ayan walang u-boot

kailangan ireprogram yung EEPROM or palitan ko na lang ng tuluyan yung SPI Flash

-- im still in the middle of development ng sarili kong SPI Flash EEPROM Programmer, pero kulang pa ko ng components para makapagtest.. (nakalimutan ko ipasabay kaninang umaga, biglaan kasi) pero dadaan naman ako sa gizmo sa monday so kailangan makumpleto na at makapagtest na kahit papaano sayang dapat kanina, long vacation pa naman ngayon

[???]

Sige sis gigz tingnan ko pinagkakaabalahan mo dyan.

Code: [Select]

cd /path/to/uboot/dir2. set tool chain (e.g. codesourcery )

Code: [Select]

export CROSS_COMPILE=arm-none-eabi-3. clean first

Code: [Select]

make distclean4. configure the build for wm8505 board

Code: [Select]

make wmt_config5. finally, build the image (u-boot.bin)

Code: [Select]
