LS1043A Debug APB Slave Address Map

Xiemens — Thu, 20 Jul 2023 09:19:19 GMT

HI, I had found Address Map for APB-AP mapped debug modules in Table 79-5. of S32V234RM.pdf https://www.nxp.com.cn/webapp/Download?colCode=S32V234RM&docLang=en

But I can't found Address Map for APB-AP mapped debug modules in LS1043ARM.pdf https://www.nxp.com.cn/webapp/Download?colCode=LS1043ARM&lang_cd=zh

Where I can get it?

BR.

Please refer to "Appendix C EPU register descriptions" in LS1043ARM.

@yipingwang

Thanks to reply.

The "Appendix C EPU register descriptions" mentioned Event Processor Debug Reservation Register n (EPRSRV0 - EPRSRV7) , Is it similar to Table 79-5. of S32V234RM?

Debug APB Component System Address

Cortex-A53A ROM Table 0x40089000
Cortex-A53 A0 Debug 0x4008A000
Cortex-A53 A0 CTI 0x40089000

For a = 0 to 7:

($DCSR_BASE + $EPU_BASE + EPRSRVa) = 0x07_0000_0000 + 0x6_0000 +
FECh + (a × -4h) = 0x07_0006_0FECh +(a × -4h)

Cortex-A53 A0 Debug 7_0006_0FECh +(0 × -4h)
Cortex-A53 A0 CTI 7_0006_0FECh + (1 × -4h)

Cortex-A53 A1 Debug 7_0006_0FECh +(2 × -4h)
Cortex-A53 A1 CTI 7_0006_0FECh + (3 × -4h)

Is that correct ??

@yipingwang Hi，What about the Latest progress of Debug Adress Map?

I have another question about CodeWarrior TAP support for Eclipse IDE and where can I get the reference document?

For CodeWarrior TAP, you need to install the latest CodeWarrior for ARMv8 11.5.12.

The attached is CodeWarrior for ARMv8 user manual.

Please refer to the following update from the AE team.

The LS1043A does not have an APB AP module in it.
