I make my leopard board according to 1.3 version.When power on,dm365 have not output 0 to RE(read enable) pin and WE(write enable) pin of nand chip.RE and WE of nand chip are always high.So leopardboard doesn't work.
I check every vcc of leopardboard,such as 1.35v,1.8v,3,3v,ok.And 24Mhz Y1 and 32k crystal Y2 have signals. sd_data0-3 and sd_clk have signals.
But LED1 and LED2 is not lighted.Nand chip doesn't work.Leopardboard doesn't work and outputs nothing to uart0.There is no any signal between DDR and DM365,same with DM365 and NAND chip.
My nand chip is K9F5608U0D,not MT29F2G08 .At first ,i think my nand chip is damaged.I replace a new K9F5608U0D.But i meet same problem.Then i think there are some solder problems.So i solder a new leopardboard.But same problem.I think it maybe a software trouble.I use dm3xx_sd_boot-6_leopard.tgz (use arm-linux-gnueabi-gcc to cross-compile) to flash my 2G sd card(not sdhc).Meet same problem.
I have no any idea to solve the problem.Could anyone help me?Thanks.
i also use arm_v5t_le-gcc to make dm3xx_sd_boot-6_leopard directory,I get bin file successfully.But I meet same problem using new made sd card.
