Hi by asking Ingenic, they send the latest windows version xburst-tools source code to me. they only support Windows system. but that will some help on your jz4760 cpu. here is the tar ball. http://downloads.openmobilefree.net/Ingneic/xburst-tools-windows/nand_card_tools.tar.bz2
BTW: one of Ingenic people. named 'Yuenshu Fong' have create a Linux version usbboot for jz4770. here is the source code: http://downloads.openmobilefree.net/Ingneic/xburst-tools-linux/ingenic_boot_v1.1.tar.bz2 On 08/16/2011 02:24 PM, Uli Raich wrote:
Hi, I am trying to adapt the Linux version of usbboot top the Ronzi A3. While most of the features now work, I still have problems to access the nand flash. I finally disassembled the device and had a look at the signals on the flash chip. I found that none of the interface signals arrive there. When I try direct GPIO, programming certain lines as output and looking at the signals on the flash chip, I have the same problem. Does anybody know, how the nand flash is connected to the jz4760 CPU? It looks like I have to enable something (a mux?) to get my signals through to the flash. Any help would be largely appreciated. Thanks Uli
