Hello everyone,
I found the difference (with the help of Koan) in the command list and cycles for the newer Atmel chip. I have a new driver now to access the flash, and it works ok. However, I still have problem with UBoot1.1.4. When I load UBoot originally into flash and run, everything works well. However, when I restart the uboot from flash again, I think uboot overwrites something in the environment variables. My environment variables become corrupt. For instance the very first sign is invalid input, output, and debug settigns on the second start up.
When I print the environment variables, I get about 8K of garbage data. I wonder what could be causing my corruption. It only occurs in the environment variables.
Hi Roman, Please show us your include/configs/at91rm9200dk.h
Ciao
Marco, Here are my latest results.
I load uboot 1.1.4 (lowlevel init is skipped) into ram through bootload.bin. I execute uboot 1.1.4 I load uboot 1.1.4 (low level init is present) into ram I copy uboot 1.1.4(low level present) into flash at 10000000 I reset with external boot juped uboot 1.1.4 loads fine I saveenv I reboot I get errors about crc and stdin,out and error I do printenv, I get 65K of . At this point I see that my env variables are corrupted.
Here is my other trial I load kernel into ram I copy (linux) kernel into flash I copy kernel from flash back to ram I execute kernel -> I get bad magic number However, the same kernel runs from ram
Somehow my data is corrupted. But why and how does the original uboot saved to flash is loading fine?
I am lost, Roman
