Other Parts Discussed in Thread: RFSDK
Hi Team,
I am working on Integrating K2L JESD with our Custom RF-Board . Our front end is initialized successfully, however when trying to form the link from K2L JESD side we see our de-framer(on our custom RF board) status showing a frame Error.
I am working on RFSDK and i modified the radio_init as below for integrating with our Front end radio config:
1. self.dfe.dfe_reset()
2. self.dfe.dfe_init()
3. self.dfe.dfeS.JesdTxInit()
4. Initialise our board through SPI from K2L.
5. self.dfe.is_jesdtx_ok()
6. self.dfe.dfeS.JesdRxInit()
Initially i am only trying to verify txlink.
| txlink (as per dfe config file) | Our Custom DAC | |||
| cf | 0 | CF | 0 | |
| f_m1 | 3 | 4 | F | 4 |
| k_m1 | 31 | 32 | K | 32 |
| l_m1 | 1 | 2 | L | 2 |
| loopback | 0 | NA | NA | NA |
| m_m1 | 3 | 4 | M | 4 |
| n_m1 | 15 | 16 | N | 16 |
| nprime_m1 | 15 | 16 | N' | 16 |
| s_m1 | 0 | 1 | S | 1 |
However when i check the jesdstatus as mentioned in the 5th point i do not see any sync update and hence jesdstatus fail.
Can we get some help in understanding self.dfe.dfeS.JesdTxInit() functionality to check if the other end is actually receiving some PRBS (pseudo random bit sequence). Kindly throw some light on this.
Thanks & Regards,
