nfapi/CHANGES.md

+# Changelog
+
+### 14/06/20
+* we are not clear on how the parameters are extracted from the config file
+* in ssc struct
+* for some values it is okay and for others it is zero (in `config_request`)
+* This causes Assertion Failures leading to termination on PNF side.
+
+### 15/06/20
+* The values to config request are assigned in: `config_common()` in `config.c`
+* need to add lines for `cfg->nfapi_config`
+* the config request unpacked on pnf side still has some zero values, which causes assertional failure in from_nrarfcn()
+
+### 16/06/20
+* Config request is recived and unpacked correctly
+* Regarding config response
+    * we are confused about its' struct definition
+    * it says list of TLVs in its entirety
+    * and we need to dyanmically insert the invalid TLVs after checking in a categorical fashion
+    * Need to think of a data structure to enable this feature.
+    ```struct{
+    list of uint8_t tlvs
+    list of uint16_t tlvs
+    list of uint32_t tlvs
+    }list of tlvs
+    ```
+* Need the `N_RB` value to be non-zero and obtained from the config file. (carrier config grid size)
+`int N_RB = gNB_config->carrier_config.dl_grid_size[gNB_config->ssb_config.scs_common.value].value;`
+* how is this `gNB_config` assigned its values?
+
+### 19/06/20
+* `ret = openair0_device_load(&ru->rfdevice,&ru->openair0_cfg);` sloc: 1428 in `nr-ru.c`
+* the `ru->rfdevice` has all members zero or null.
+* This issue was solved by adding `sdr_addrs` to config file of PNF.
+
+* `if (cfg->tdd_table.max_tdd_periodicity_list[nr_tti].max_num_of_symbol_per_slot_list[symbol_count].slot_config.value==1`
+    * throws segmentation error
+    * `max_tdd_periodicity_list` is not assigned memory
