Dear all
I'm using the or1200 processor on FPGA right now, but I've had a lot of problems
The problem is focused on the loading board, when I send the data (orpmon/) to the board. Here is my logs of the questions.Thanks !

1.The first question
There are many reading errors here, although it is best to be ready for the JTAG chain at the end

2.The second question
And,the JTAG was exited the connection when I executed this command.

3.The third question
Neither the CPU nor the sdram detected it at the time of self-testing

Thank you very much for your help,
Zengfeima

are you chinese? have you solve this problem?

hello:
I want you ask that have you solve the problem?

good luck!

Hi,

Thank you for your concern! I'm from Chengdu, China, and I haven't completely solved this problem, because I've been so busy lately. I'm going to get this done next month or rebuild a system with mor1kx. Excuse me, if you have any good ideas, maybe we can try together. Are you from China, too? Maybe we can talk about it!
