Please refer the API CyU3PSibSetPasswd in the FX3 API Guide. This is used to set the password.

Hello madhu,

Thanks for reply. I have made call of Api CyU3PSibSetPasswd(0,0,aucPwd,2,aucPwd,2) after finishing partition sd card. First i have defined uint8_t aucpasswd[2] ={ 'h','i'}.i am using msc example in fx3 sdk.After downloading .img in to cyusb 3025 based hardware,the card is locked ,and also system doesn't ask for password.If i took the card and try to read in another computer  ,the card is not visible to the computer .

kindly tell where should i  call the Api CyU3PSibSetPasswd in the code and please tell how to enter the password through pc to sd card .


thanking you in advance
