1. Re: Build error: ERROR: L257: UNKNOWN
Actually there's more to the error:
******************************************************************************
* RESTRICTED VERSION WITH 0800H BYTE CODE SIZE LIMIT; USED: 03A8H BYTE (45%) *
******************************************************************************
Program Size: data=68.4 xdata=1019 const=504 code=15230
*** ERROR L257: UNKNOWN
The command 'LX51.exe' failed with exit code '3'.
I don't believe there are any code size limitations on the CA51 compiler? Also, is this message saying that we're using 0x03A8 = 936 bytes, while the limit is 0x0800 = 2048 bytes? So it's under the limit?

I tried completely uninstalling and reinstalling (because I previously had the evaluation version) but it doesn't help.

Did you install LIC (register your license) with administration rights ?

Yes, μVision License Management says "C51 Compiler/Assembler Kit" "Expires: Mar 2020"

Please follow the steps mentioned here to get it working: LX51: ERROR L257: EXTENDED LINKER REQUIRES UPGRADE TO PK51

10. Re: Build error: ERROR: L257: UNKNOWN
So PSoC Creator is not compatible with CA51? It requires PK51? I thought the difference was that PK51 had more debugging features?

No, PSoC Creator should be compatible with both CA51 as well as PK51 if they have the same features. Please check if you have registered the license number which you received when you purchased the compiler and not the free PK51 license given by Cypress.

12. Re: Build error: ERROR: L257: UNKNOWN
μVision License Management says "C51 Compiler/Assembler Kit" "Expires: Mar 2020" if that's what you mean, and the PSoC Creator Build Settings is set to DP8051 Keil Generic.

13. Re: Build error: ERROR: L257: UNKNOWN
Do you have any advice on how to troubleshoot this? Is ERROR L257: UNKNOWN
the same as
L257: EXTENDED LINKER REQUIRES UPGRADE TO PK51?
So PSoC Creator is trying to use an extended linker? Is there a way to turn that off?

14. Re: Build error: ERROR: L257: UNKNOWN
Steps to reproduce:
- Open original Music Creation example project in PSoC Creator 3.3.
- Build the project using free compiler 9.51 and it works fine. (Flash used: 64256 of 65536 bytes (98.0 %). SRAM used: 6373 of 8192 bytes (77.8 %).))
- Install C51V959.exe to C:\Keil_v5
- Open Keil μVision → File → License Management → Single-User License → Enter LIC code
- It now says "C51 Compiler/Assembler Kit", and " Expires: Mar 2020"
- PSoC Creator: Tools → Options → Project Management → 8051 Toolchains → DP8051 Keil Generic
- Set it to C:\Keil_v5\C51\BIN
- Project → Build Settings
- Change to Generic Toolchain and set all settings to the same as 9.51.
- Build project, it doesn't work.
- Try changing increasing optimization level, turning off Linker Code Packing, Debug vs Release, etc., it still doesn't work:
