Hi,
I have downloaded MDK539.EXE and installed, and tried to get the license from License management option of Keil ide menu.
MDK539.EXE (935,160K)Saturday, December 2, 2023
While trying to complete the license activation from https://www.keil.com/license/install.htm
, i get this below error
The Product Serial # (PSN) may not be blank.
I have not received the PSN through email. I want to use Arm Compiler for Embedded FuSa 6.16.2
Please send the details on how to get the license and use the compiler in Keil uvision5 IDE.
Hello Benny,
Have you purchased a license? To use Arm Compiler for Embedded FuSa 6.16.2, you require an MDK Professional Edition license:
https://developer.arm.com/Tools%20and%20Software/Keil%20MDK#Editions
The link you reference is for the Single User license format. You may have a different license format:
https://developer.arm.com/documentation/101454/0103
I recommend contacting your sales representative, or raising an support case from the menu above to discuss with Arm privately.
Thanks, Ronan. In addition...

See the below.

This is or non-commercial use only, and does not enable the FuSa compiler. It does however contain the standard Arm Compiler for Embedded.
Thanks, with this compiler i'm able to compile. However, i got an error while building simple HelloWorld C program.
.\firstproject.sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST.
Scatter file generated by uVision is as below,
; *************************************************************; *** Scatter-Loading Description File generated by uVision ***; *************************************************************
LR_IROM1 0x00400000 0x00200000 { ; load region size_region ER_IROM1 0x00400000 0x00200000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) .ANY (+XO) } RW_IRAM1 0x20400000 0x00018000 { ; RW data .ANY (+RW +ZI) }}
The error is induced by this line in the scatter file:
*.o (RESET, +First)
Have you included the Device startup code from the CMSIS Pack? This should set the Vector table at this location.
Alternatively, simply comment this line out (place semi-colon ";" at start of line).
No, i havn't included CMSIS pack, which i don't want to.
Yes, i commented the line but since its auto generated every time it creates new and not taking the modified one.
In Target Options > Linker, deselect "Use Memory Layout from Target Dialog", and then specify your own scatter file.
Hi Ronan,
I created a new uvision project and included CMSIS, core and startup file, and also selected IO for stdio.h to ITM.
Added a simple Helloworld print c file. While compiling it throws this error,

Please help in resolving above issue.
You should define a region ARMLIB_STACKHEAP in your scatter file:
