（1）如果工程直接復(fù)制另一個(gè)工程，路徑一定要修改，建議重新eclipse工程。

（2）clean Project時(shí)提示rm: can't remove 'build/dhrystone.elf': Permission denied

正在使得該elf文件，上次的JTAG鏈接沒(méi)有斷開(kāi)。此時(shí)可以先關(guān)閉c/c++工作界面，再重新添加C/C++(default),然后在Console中關(guān)閉上次的鏈接。

（3）Debug session'default' already started。

先關(guān)閉c/c++工作界面，再重新添加C/C++(default),然后在Console中關(guān)閉上次的鏈接。

(3)Memory region Used Size Region Size %age Used

c:/efinity/sdk_windows/riscv-xpack-toolchain_8.3.0-2.3_windows/bin/../lib/gcc/riscv-none-embed/8.3.0/../../../../riscv-none-embed/bin/ld.exe: build/ti60f225_oob.elf section `.bss' will not fit in region `ram'

ram: 2363296 B 1 MB 225.38%

c:/efinity/sdk_windows/riscv-xpack-toolchain_8.3.0-2.3_windows/bin/../lib/gcc/riscv-none-embed/8.3.0/../../../../riscv-none-embed/bin/ld.exe: region `ram' overflowed by 1314720 bytes

collect2.exe: error: ld returned 1 exit status

make: *** [../common/standalone.mk build/ti60f225_oob.elf] Error 1

解決辦法：Error的意思是外部存儲(chǔ)器的存儲(chǔ)空間不夠，目前在分配了1MB的情況下使用了225.38%。所以把default.ld中的LENGTH 修改成4M.

重新編譯后的結(jié)果。

（4）Error: libusb_get_string_descriptor_ascii() failed with LIBUSB_ERROR_PIPE

Error: no device found

Error: unable to open ftdi device with vid 0403, pid 6014, description 'ELITES-232DL', serial '*' at bus location '*'

原因：把embedded_swsoc_xxbspefinixEfxSapphireSocopenocdftdi.cfg（ftdi_ti.cfg）修改成下載器讀出來(lái)的名字，比如這里我把ELTES-232DL修改成了Trion T120F324 Development Board。因?yàn)镻rogrammer界面讀到的USB target就是Trion T120F324 Development Board，當(dāng)然也要注意ftdi_vid_pid和ftdi_channel是否正確，如果不正確也會(huì)引起別的問(wèn)題。

(5)Error:cpuConfigFileD:testriscvefx_ti60f225_oob_v2.1embedded_swsapphire_soccpu0.yaml not found

Error: target 'fpga_spinal.cpu0' init failed

原因：debuger路徑問(wèn)題。在riscv和efx之間應(yīng)該有個(gè)斜杠，如報(bào)錯(cuò)中的紅色標(biāo)注。

（6）No source available for "main() at 0x1114"

原因：沒(méi)有打開(kāi)debug環(huán)境變量。打開(kāi)debug開(kāi)關(guān)之后要重新編譯。

(7)Error: timed out while waiting for target halted

原因：1）IP設(shè)置的是soft Jtag,實(shí)際卻用hard Jtag在調(diào)試；

2）CPU沒(méi)有跑起來(lái)；

3）debuger與JTAG沖突；

4）在interface 添加JTAG之后生成的信號(hào)與RISCV 連接不正確或者不完全。

5)AXI接口連接異常，也可能出現(xiàn)timed out指示。

（8）SOC燒寫到flash啟動(dòng)不了

一般默認(rèn)片上RAM選擇了4K大小用于bootloader，但是如果手動(dòng)修改了bootloader，比如添加了debug,可能存儲(chǔ)空間不足。

(9)

Error:JTAG scan chain interrogation failed :all ones

Error: CheckJTAGinterface,timings,target power, etc.

Error: Trying to use configured scan chain anyway...

Error: fpga_spinal.bridge: IR capture error:saw ox0f not 0x01

workround:JTAG下載線連接不緊。

（10）soft Jtag與hard Jtag同時(shí)使用時(shí)，會(huì)出現(xiàn)第一次debug都需要重新插拔下載器問(wèn)題

workround：查找兩個(gè)下載線的連接位置，注意分開(kāi)兩個(gè)下載器的連接位置。

（10）soc IP生成不了，

workround可能是java 8沒(méi)有安裝

(11) No source available for "(gdbi2),proc[42000j,threadGroupi1],gdb(2),proc420001.0Sthread[1).thread(1j.framel0j'

說(shuō)明：外部存儲(chǔ)器沒(méi)有運(yùn)行起來(lái)

（12）錯(cuò)誤：

mkdir: can't create directory 'build/xxx/embedded_sw/sapphire_soc/software/standalone/uartInterruptDemo/': No such file or directory

make: *** [../common/standalone.mk build/xxx/embedded_sw/sapphire_soc/software/standalone/uartInterruptDemo/src/main.o] Error 1

"make all" terminated with exit code 2. Build might be incomplete.

WorkWround : Eclipse路徑太長(zhǎng)。

在common文件夾下，找到standalone.mk文件。

把路徑：

OBJS := $(realpath $(OBJS))

修改成：

OBJS := $(addprefix $(PROJ_NAME)/,$(OBJS))

如下圖所示（感謝客戶為我們提供解決方案）

（13）Debug時(shí)出Break at address"0xf90000000" with no debug information avalibale,oroutside of program code

(14)

Info : JTAG tap: fpga_spinal.bridge tap/device found: 0x10660a79 (mfg: 0x53c (Efinix Inc), part: 0x0660, ver: 0x1)

Warn : Target was in unknown state when halt was requested

Info : Halt timed out, wake up GDB.

Error: timed out while waiting for target halted

原因（1）RISCV中FPGA Top Port選擇不對(duì)。

（2）確認(rèn)下載線連接是否正常。

（13）

(1) 同一個(gè)下載器時(shí)softjtag與hardjtag的名字不能一樣，比如一個(gè)是YLS_DL,另一個(gè)是YLS_DL1.也就是需要手動(dòng)把另一個(gè)名字修改下。

(2)注意修改cfg文件時(shí)文件時(shí)的channel號(hào)要與下載器對(duì)應(yīng)

(14)

（1）用2022的版本打開(kāi) 2023版本的工程報(bào)這個(gè)錯(cuò)誤 ，新版本已經(jīng)不再使用c232hm_ddhsl.cfg文件，而是改用external.cfg文件 。
