## NXP LS1028A
1078+
1079+
The LS1028A is a AARCH64 armv8-a Cortex-A72 processor. Support has been tested with the NXP LS1028ARDB.
1080+
1081+
Example configurations for this target are provided in:
1082+
* NXP LS1028A: [/config/examples/nxp-ls1028a.config](/config/examples/nxp-ls1028a.config).
1083+
* NXP LS1028A with TPM: [/config/examples/nxp-ls1028a-tpm.config](/config/examples/nxp-ls1028a-tpm.config).
1084+
1085+
### Building wolfBoot for NXP LS1028A
1086+
1087+
1. Download `aarch64-none-elf-` toolchain.
1088+
1089+
2. Copy the example `nxp-ls1028a.cofig` file to root directory and rename to `.config`
1090+
1091+
3. Build keytools and wolfboot
1092+
1093+
```
1094+
cp ./config/examples/nxp-ls1028a.config .config
1095+
make distclean
1096+
make keytools
1097+
make
1098+
```
1099+
1100+
This should output 3 binary files, `wolfboot.bin`, `image_v1_signed.bin` and `factory.bin`
1101+
- `wolfboot.bin` is the wolfboot binary
1102+
- `image_v1_signed.bin` is the signed application image and by default is `test-app/app_nxp_ls1028a`
1103+
- `factory.bin` is the two binaries merged together
1104+
1105+
1106+
### Hardware Setup LS1028ARDB
1107+
1108+
DIP Switch Configuraiton for XSPI_NOR_BOOT:
1109+
```
1110+
SW2 : 0xF8 = 11111000 SW3 : 0x70 = 01110000 SW5 : 0x20 = 00100000
1111+
Where '1' = UP/ON
1112+
```
1113+
1114+
UART Configuraiton:
1115+
```
1116+
Baud Rate: 115200
1117+
Data Bits: 8
1118+
Parity: None
1119+
Stop Bits: 1
1120+
Flow Control: None
1121+
Specify device type - PC16552D
1122+
Configured for UART1 DB9 Connector
1123+
```
1124+
1125+
### Programming NXP LS1028A
1126+
1127+
Programming requires three components:
1128+
1. RCW binary - Distribured by NXP at `https://github.com/nxp-qoriq/qoriq-rcw-bin` or can be generated using `https://github.com/nxp-qoriq/rcw/tree/master/ls1028ardb/R_SQPP_0x85bb` (tested with `rcw_1300.bin`)
1129+
2. woflBoot
1130+
3. Application - Test app found in `test-app/app_nxp_ls1028a.c`
1131+
1132+
Once you have all components, you can use a lauterbach or CW to flash NOR flash. You must flash RCW, wolfboot and singed_image. `factory.bin` can be used which is wolfboot and the signed image merged. You will need to build a signed image for every update to the application code, which can be done by using keytools in `tools/keytools/sign` see `docs/Signing.md` for more details
1133+
and to sign a custom image.
1134+
1135+
```
1136+
Usage: tools/keytools/sign [options] image key version
1137+
```
1138+
1139+
#### Lauterbach Flashing and Debugging
1140+
1141+
1. Launch lauterbach and open the demo script `debug_wolfboot.cmm`.
1142+
2. Open any desired debug windows.
1143+
3. Hit the play button on the demo script.
1144+
4. It should pop up with a code window and at the reset startpoint. (May requrie a reset or power cycle)
1145+
1146+
```
1147+
./t32/bin/macosx64/t32marm-qt
1148+
1149+
Open Script > debug_wolfboot.cmm
1150+
```
1151+
1152+
You can modify the Lauterbach NOR flash demo or use `debug_wolfboot.cmm` script, just make sure the flash offset for
1153+
the RCW is `0x0` and the address offset for wolboot is `0x1000`.
1154+
1155+
#### Other Tools
1156+
1157+
1. Make sure the memory addresses are alinged with the `.config` file.
1158+
2. Note the important NOR flash addresses in the defualt config are as follows.
1159+
3. RCW location is offset `0x0` or `0x20000000` memory mapped.
1160+
4. Wolfboot location is offset `0x1000` or `0x20001000` where wolfboot starts.
1161+
5. Application location is offset `0x20000` or `0x20020000` where application code goes.
1162+
6. Update location is offset `0x40000` or `0x20040000` where the new or updated applciaiton goes.
1163+
7. Load Location is `0x18020100` which is OCRAM or where the applciaiton code is loaded if using RAM loading from
1164+
8. DTS Location is
1165+
9. Update memory locations as neeeded.
