剛買RTL8195A 發展版, 經開機會動作 如WLAN SCAN...., 我放一段時間 USB DISCONNECT
再拔插USB後 及 RERUN SecureCRT, 顯示如下:
ROM Version: 0.3
Build ToolChain Version: gcc version 4.8.3 (Realtek ASDK-4.8.3p1 Build 2003)
Check boot type form eFuse
Image1 length: 0x0, Image Addr: 0x0
Image1 Validation Incorrect !!!
Please Re-boot and try again, or re-burn the flash image
PS: Board can switch NON DAP and DAP SUpport
Sean, thanks again your help, however, I understand the 8195AM hardware structure and share information for beginner as below
When pressed both key as DAP update mode + DAP reset button before power ON, the mBed Disk driver(lable: CRP_DISABLE) will be appeared and size is 64KB that is LPC11 firmware not “8915 wifi binary”. You can copy&paster file “DAP_FW_Ameba_V10_2_3-2M.bin” or “DAP_FW_Ameba_V10_2_3-2M_LED_Disable.bin” into disk to update LPC11U35 firmware.
When DAP download mode (pressed DAP reset again) , the computer will be appeared a disk as “mBed microcontroller USB device” and disk size is 2M that is for 8195A application binary firmware upgrade, meantime, USB serials also turn ON, You can copy “ram_all.bin to disk” on your complier “EXE” folder and remove disk , replug cable, You can see application running on Terminal.
Ps: dap switch function was dead, reset key mal-function
but it is not working, 不能燒 ram_all.bin, 板子完全沒反應，只剩 flask disk, serial port 沒有 （裝置描訴錯誤），感覺硬體穩定度不好，對flash 保護有問題
jtag not working, 如何燒 image again
