Hardware Reference Manual for i.MX53 Quick Start
?
?
The ? first ? question ? that ? the ? user ? will ? be ? asked ? by ? the ? OBDS ? test ? is ? if ? the ? user ? would ? like ? to ? AUTORUN ? the ?
OBDS ? test. ? A ? yes ? answer ? (y ? or ? Y) ? will ? keep ? the ? OBDS ? test ? from ? prompting ? the ? user ? for ? any ? test ? that ? does ?
not ? require ? direct ? user ? action. ? Any ? other ? key ? press ? will ? cause ? the ? OBDS ? test ? to ? prompt ? for ? all ? tests. ? A ? yes ?
answer ? to ? this ? question ? is ? primarily ? for ? mass ? testing ? of ? Quick ? Start ? boards. ? Single ? users ? of ? this ? test ? can ?
run ? this ? test ? with ? prompts ? without ? significant ? loss ? of ? time. ?
?
The ? tests ? are ? straight ? forward, ? and ? if ? a ? supporting ? piece ? of ? equipment ? is ? required, ? the ? test ? will ? prompt ?
the ? user ? for ? it. ? In ? order ? to ? complete ? all ? the ? tests, ? you ? would ? need ? to ? have ? the ? following ? equipment: ?
?
USB ? HOST1 ? Test ? – ? Attached ? USB ? device ? required ?
SATA ? Test ? – ? Attached ? SATA ? device ? required. ?
Ethernet ? Test ? – ? The ? Ethernet ? loop ? back ? test ? plug ? as ? described ? below ? is ? required. ?
Head ? Phone ? Test ? – ? A ? set ? of ? earphones ? or ? speakers ? are ? required. ?
LCD ? Test ? – ? The ? optional ? LCD ? Display ? card ? is ? required ?
LVDS ? Test ? – ? The ? optional ? LVDS ? display ? kit ? is ? required ?
VGA ? Video ? Test ? – ? Connection ? to ? a ? VGA ? monitor ? is ? required ?
HDMI ? Test ? – ? The ? optional ? HDMI ? card ? is ? required ?
MMC/SD ? Card ? slot ? – ? A ? full ? size ? SD ? card ? is ? required ? in ? card ? slot ? J5. ?
?
If ? the ? developer ? does ? not ? have ? one ? or ? more ? of ? the ? above ? items, ? the ? test ? can ? easily ? be ? skipped ? when ?
asked ? if ? the ? user ? would ? like ? to ? perform ? the ? test. ? A ? complete ? cycle ? of ? tests ? covers ? 16 ? different ? aspects ? of ?
the ? board. ? When ? the ? last ? test ? is ? run, ? the ? OBDS ? tool ? will ? print ? out ? a ? summary ? of ? the ? test ? results. ? A ? failure ?
in ? any ? one ? particular ? area ? would ? indicate ? that ? there ? is ? a ? hardware ? fault ? with ? the ? Quick ? Start ? board ? that ?
should ? be ? addressed. ? If ? all ? tests ? pass, ? but ? the ? developer ? code ? does ? not ? function ? correctly, ? the ? problem ? is ?
most ? likely ? with ? the ? code. ? A ? more ? detailed ? description ? of ? the ? tests ? is ? as ? follows: ?
?
1) MAC ? Address ? confirmation. ? The ? i.MX53 ? Processor ? reads ? the ? MAC ? Address ? programmed ? into ? the ?
Processor ? eFUSEs ? and ? prints ? them ? out ? on ? the ? terminal ? window. ? The ? resulting ? print ? out ? should ?
match ? the ? MAC ? address ? label ? on ? the ? Quick ? Start ? board. ? If ? the ? two ? numbers ? match, ? the ? test ? has ?
passed. ?
?
2) UART ? Test. ? When ? the ? test ? is ? running, ? the ? test ? expects ? different ? characters ? to ? be ? input ? from ? the ?
keyboard ? of ? the ? host ? computer. ? After ? a ? character ? is ? input, ? the ? i.MX53 ? Processor ? receives ? the ?
input, ? transmits ? to ? the ? terminal ? window ? the ? received ? character, ? and ? then ? asks ? the ? user ? to ?
confirm ? that ? the ? character ? is ? correct ? by ? pressing ? the ? ‘x’ ? key. ? The ? test ? is ? exited ? by ? typing ? an ? ‘x’ ? as ?
an ? input ? character. ?
?
3) DDR ? Test. ? The ? test ? writes ? predetermined ? data ? onto ? the ? DDR3 ? memory, ? reads ? those ? memory ?
blocks ? back ? out, ? and ? then ? compares ? the ? two ? values ? for ? errors. ? If ? the ? values ? match, ? the ? test ?
passes. ?
?
4) USBH1 ? Enumeration ? Test. ? Any ? USB ? device ? is ? plugged ? into ? the ? upper ? HOST ? connector ? (the ? lower ?
port ? is ? connected ? to ? the ? USBOTG ? module). ? After ? confirming ? that ? a ? USB ? device ? is ? plugged ? in, ? the ?
I.MX53 ? will ? read ? the ? device ? enumeration ? data ? and ? print ? it ? out ? on ? the ? terminal ? window. ? If ? the ?
Processor ? cannot ? read ? enumeration ? information, ? the ? test ? fails. ?
