Was one of the sectors you erased the first sector? If so that is your problem, the hard reset word is located in the beginning of the first sector. To fix this you need to do the following. 1. There is a resistor that is removed from the board at location RO2. This resistor sets the default hard reset word. You have to put a 0ohm resistor at this location, a solder glob will also work. 2. Download the Planet Core FLASH burner and execute it. Give the command hrw to reburn the hard reset word. If the processor is 233MHz or higher give the command hrw h. 3. Remove the 0ohm resistor(or solder glob) at RO2. -----Original Message----- From: deepesh@india.tejasnetworks.com Sent: Tuesday, July 22, 2003 3:33 AM Subject: EP8260 I loaded my EP8260 board with UBOOT. This was working fine. Then I loaded a binary into RAM using tftp. Then tried copying the stuff to flash. When I could not copy things into flash directly, I erased a few sectors randomly and then copied the binary to flash. Then when I reset the board, it did not come up. I put back the u-boot into the flash using BDI2000. But now I am getting weird characters on the screen. I have looked at the minicom settings-- It is 115200 and 8N1. These were the settings with which I was working before also. What I am not able to understand is the reason for the weird characters. I am attaching the weird character file. The last line seems to be the U-BOOT prompt. I tried changing the TERMINAL SETTINGS to ANSI from VT100, but it did not help. ------------------------------------------------------------------------ ?åêáó`*m,ïïô`0nsnp`hSõì rr`r0ps`m@qrzs2zrvi ??fxrv0`?åóåô`?ôáôõóz@?øôåòîáì`?ïæôl ?øôåòîáì`Èáòä ??fxrvp fìïãë`fïîæéçõòáôéïî `m`,õómôïmfïòå`?õìô`snuøl`-f?`?éö rl`v0ø`,õó`?òåñ``sp-xu`l fïòå ?òåñ qppm3pp `m`äæâòç`q,`ãïòåãîæ`0øqål`âõóäæ`rl`ãðíäæ`ql`ðììäæ`ql`ðììíæ`r `m`öãïYïõô``qyxppp0ppl`óããYãìë```tyupppppl`âòçYãìë```1rswup0p `m`ãðõYãìë` rsqpppppp,`ãðíYãìë`@`yyp0ppppL`âõóYãìë```vvp0pppp f?*z`` ??fxrvp`h?åö`q4l`?áóë`?n0h?i`r<ru?)`áô`2sq`?Èú ,ïáòäz ?íâåääåä`?ìáîåô`??x2vpl`?åöéóéïî`p.p ?2fz`` òåáäù ????z `vt`?, ????^:`qv ?, jjj`-áòîéîç`m`âáä`f?fl`õóéîç`äåæáõìô`åîöéòïîíåîô ?îz` ``óåòéáì ?õôz ``óåòéáì ?òòz ``óåòéáì ?Åôz```?ffs`??^????? ,??,*?zòåÁäù }~` -------------------------------------------------------------------------- ** Sent via the linuxppc-dev mail list.
