Part Number:AM2732Other Parts Discussed in Thread:UNIFLASH, TIDA-020047
hi,
我使用python uart_uniflash.py烧录我们自己打样的TIDA-020047板子,烧录失败,监测串口数据,无数据下发,如下图,请问是什么原因?

在上电之后,我在串口调试助手里面 看不到 字符 “C”

请问您的板子和TIDA-020047一模一样吗?同样的操作在TIDA-020047可以吗?
,
miles meng:
模块问题,换个模块就行了
,
miles meng:
第一个指令正常了,第二个指令 无响应,是什么情况呢?

miles meng:
你好,是用的TIDA-020047的打板资料做的板子,PMIC电源还没有输出,调了半个月了,现在是外部给各路电源供电来调的。

cfg文件如下:
#—————————————————————————–## ## DEFAULT CONFIGURATION FILE TO BE USED WITH THE FLASHWRITER SCRIPT ## ##—————————————————————————–### By default this config file,# – points to pre-built flash writer, bootloader for this EVM# – The application image points to relative path of the ipc echo application image for this EVM# – Make sure this application is built before running this script# – You can customized this config file to point to your own bootloader and/or application images# – You can use –operation=flashverify if you just want to verify the flash contents and not flash the file.#
# First point to sbl_uart_uniflash binary, which function's as a server to flash one or more files–flash-writer=sbl_prebuilt/am273x-evm/sbl_uart_uniflash.release.tiimage
# Now send one or more files to flash or flashverify as needed. The order of sending files does not matter
# When sending bootloader make sure to flash at offset 0x0. ROM expects bootloader at offset 0x0–file=sbl_prebuilt/am273x-evm/sbl_qspi.release.tiimage –operation=flash –flash-offset=0x0
# send the application image to flash. Flash it at 0xA0000 as the SBL expects it at this location–file=sbl_prebuilt/am273x-evm/empty_system.appimage –operation=flash –flash-offset=0xA0000

建议先检查一下板子硬件问题,PMIC电源的输出问题先解决一下。

miles meng:
外部供电,可以烧录第一个文件了呀,为什么第二个文件烧录不了呢?可能会在哪些地方存在问题?
,
Shine:
可以先在TIDA-020047操作一下,同样的代码,同样的操作步骤如果在EVM板上可以的话,那就可能是板子的硬件问题了。
