Part Number: AM2434
Other Parts Discussed in Thread: UNIFLASH
We're looking for upgrade our legacy C6424 based HW for a new AM243x platform.
My setup is: AM324X-LP connected to Win10 + ccs2100 + mcu_plus_sdk_am243x_12_00_00_27 + ind_comms_sdk_am243x_2026_00_00_06 + motor_control_sdk_am243x_09_02_00_12
AM324X-LP boot mode: UART. PC can receive sequence of "c" at COM4 at 115200
I'm trying to flash the pre-built version of the "sbl_null.release.hs_fs.tiimage" via "sbl_uart_uniflash.release.hs_fs.tiimage" as example.
CMD: python uart_uniflash.py -p COM4 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg
CFG:
--flash-writer=sbl_prebuilt/am243x-lp/sbl_uart_uniflash.release.hs_fs.tiimage
--file=sbl_prebuilt/am243x-lp/sbl_null.release.hs_fs.tiimage --operation=flash --flash-offset=0x0
Problem:
uart_uniflash.py successfully sending the sbl_uart_uniflash to device but then communication stopped. My assumption is the control has to be given to sbl_uart_uniflash code and it should continue with the reading from COM and flash received data. But there's no such communication. Error message:

[ERROR] XMODEM send failed, no response OR incorrect response from EVM OR cancelled by user,
Power cycle EVM and run this script again !!!
COM port stays connected at WIN10 and I still can see the "c" stream immediately after of error described above.
Any suggestions?
