Date: Wed, 2 Jun 2004 21:55:57 +0200 (MEST) I tried to upgrade my non-flashable jukebox (recorder 20) with a new flash chip today, but I need some help with [IDC]Dragon's uart_boot tool. I started with doing the serial mod and the uart boot mod. Then I tried if those two mods were succesful by hooking it up to my computer and testing the uart_boot tool. I tried the following scenarios: a) 1. jukebox off, UART boot mod enabled (LCD lines driven low) 2. uart_boot -p COM1 -r -a -b 3. power-on jukebox Result: uart_boot is waiting for box startup endlessly b) 1. jukebox off, UART boot mod disabled (original state) 2. uart_boot -p COM1 -r -a -b 3. power-on jukebox Result: uart_boot displays some menu (like [IDC]Dragon described it in his early posts about the UART boot mod) and complains that it can't find minimon_v2.bin c) 1. UART boot mod enabled 2. power-on jukebox 3. uart_boot -p COM1 -r -b Result: LED is flashing as expected Since I didn't really now what the -archos option does, I thought it worked and started soldering in the flash chip. Afterwards I tried flashing the new chip with uart_boot -p COM1 -r -f firmware_rec.bin and it looked as if it was successful, but it wasn't. If I dump the contents of the flash, I get something completely different. But, the uart_boot seems to work, since flashing the led works, the harddisk-shutdown works and the readout of the flash id works as well (I get 0xBF, 0xD6 with the new chip) Any ideas? Could it be a hardware error, for example that I didn't solder it in properly? But I guess that it wouldn't read out the IDs then. Thank you, Andreas _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-06-02 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
