New engineering configuration method of Renesas + for CC:

2022-04-23 22:08:00 【InfoQ】

In the last post , We talked about Reza

IDE：CS+ for CC download 、 Installation and basic use

, After creating a new project and generating the sample code , Edit project , Error message , As shown below ：

The main reason is that the new project needs to be configured before it can be compiled and run normally .

1、 To configure boot.asm file

Visible in the project bar boot.asm file , As shown below ：

The first 1 Step ： Get rid of USE_TABLE_REFERENCE_METHOD .set 1 Previous “ ;”, Make the project support interrupt function , As shown below ：

The first 2 Step ： Configure interrupt vector , take .section "RESET", text and .section "EIINTTBL", const The interrupt that needs to be used opens , Add interrupt callback function , Unused interrupts default to #_Dummy_EI, In the project, all interrupt vectors are set to no use state by default , As shown below ：

for example , Generated in the last blog post UART0 Sample code , At this time, the interrupt cannot be triggered normally , You need to open the corresponding interrupt vector .

With r_uart0_interrupt_receive,UART0 Take the interrupt receiving callback function as an example ,channel=35, You need to add an interrupt callback function to the same interrupt vector , stay .section "EIINTTBL", const Add after , That is, the callback function name （ Be careful ： The callback function name should be preceded by _）, Replace as Dummy_EI, As shown below ：

The first 3 Step ： To configure RAM Area , According to the data book and requirements, the LOCAL_RAM_ADDR And LOCAL_RAM_END Configure related values , As shown below ：

2、 To configure cstart.asm file

Configure heap STACKSIZE, The default value is 0x200, It can be modified as needed , As shown below ：

3、 prohibit r_cg_main.c、r_cg_intvector.c Files participate in compilation

On the left side of the project Project Tree in , choice ：

File→Code Generator→r_cg_main.c and r_cg_intvector.c

, Right click on the file , choice Property, Set up Set as build-target by NO, As shown below ：

4、 To configure Debug Tool

On the left side of the project Project Tree in , find Debug Tool, Right click selection ：Using Debug Tool, Choose your own burning tool （ What I'm using here is RH850 E1（LPD））, As shown below ：
