HI
I use TJA1100 on my board,but i have some problems
The TJA1100 can`t work on my board ,so i did some tests,the result is:
register | internal | extend | remote | normal |
0 | 24832 | 24832 | 24832 | 8448 |
1 | 485 | 481 | 481 | 481 |
15 | 128 | 128 | 128 | 128 |
17 | 40391 | 40399 | 40415 | 40391 |
18 | 22545 | 22545 | 22545 | 22545 |
19 | 8773 | 8773 | 8773 | 8773 |
20 | 0 | 0 | 0 | 0 |
21 | 544/512? | 32928/160? | 160 | 160/128? |
22 | 32768 | 32768 | 32768 | 32768 |
23 | 48132(send_n) | 16388(send_i) | 24580(send_z) | 24580(send_z) |
24 | 16896 | 16896/512? | 16896 | 16896/512? |
25 | 0 | 0 | 0 | 0 |
26 | 0 | 0 | 0 | 0 |
The same register may have different value in the same mode,for example,the register 21. it make me confused.
Reg21 | power-on detected | training phase failure detected
| SMI control error detected
|
544 | 0 | 0 | 1 |
512 | 0 | 0 | 0 |
32928 | 1 | 1 | 1 |
160 | 0 | 1 | 1 |
128 | 0 | 1 | 0 |
Reg24 | PLL stable and locked | hardware reset detected since register last read |
16896 | 1 | 1 |
512 | 0 | 1 |
The excel shows that the internal mode work well, but the extern mode,the remote mode and the normal mode link failure.
How to make it work fine in normal mode?
Solved! Go to Solution.
Decimal values in your tables are not well readable. Can you convert them to hex ones to get better bit-map structure?
At the moment I looked at register #17 in normal mode, value 40391 (that is 0x9DC7) shows following
SLAVE_JITTER_TEST = Enable;
TEST_MODE = reserved;
WAKE_REQUEST = 1 (transmit idle symbols as bus wake-up request).
Same value is in "internal mode". Are those values expected?

Hi
The problem had been solved,the tja1100 was broken on hardware.
