content: Hi there , I have posted a while back about a gps that I was messing around with. Well I flashed it , I know I know. If it's forever gone so be it. Well my question is can I some how flash the back up content back ? I noticed it has mdoc API port on board with flash_sclk,si,so,scs pins not sure what these do. And when first connected via USB Linux reads it as flash device connected but goes away as soon as device finishes loading. Any help or suggestions are appreciated. Thank youSent from my iPhone using Tapatalk

content: @cliff Mathews no it did not come with one it had all files on internal memory. In fact the ad port was hidden under a cover that was glued on . Before playing with it I did back up all files on computer. But when the gps finishs booting it says enter sd card which I do with all files in it just the way they were arranged on internal memory . Press okay and it just stays on white screenThank you for the helpSent from my iPhone using Tapatalk

content: There may be files or partitions on the SD you can't see. Back in the day, when there was anything suspect, we'd use the Black-Ice program to save wierd-arse partition tables. In retired from that scene now, but this could relate to your problem.http://forums.gpsreview.net/discussion/9645/magellan-1412-and-no-map-sd-card

content: So after reading your link and several others, I have all the correct files in the order they are in. I'm wondering if it just needs to be certain files and not all of them. If there is nothing I can do , that is okay it was a learning experience to start with and plus side I have a little tracing board now for small pcb layouts lol for future knowledge any chance do you or anyone know how to use the mdoc spi port ?Sent from my iPhone using Tapatalk
