Other Parts Discussed in Thread: LP-AM243
Tool/software:
Hi team,
We uses AM243x_lp to build a custom flash ic board integrating an OSPI-Flash from Macronix. The flash used is the MX25L25645GM2I-08G.The SDK version I am using is mcu_plus_sdk_am243x_09_00_00_35.
I replaced the LP-AM243's external flash with an MX25L25645GM2I-08G.I checked the SDK instructions and found an article on how to apply custom flash to the LP.
Based on that, I attempted to update the flash parameters using our chosen flash data sheet and the.json file included with the SDK.
I've attached the. Json file for the MX25L25645GM2I-08G flash IC. Have the MX25L25645G settings been setup correctly in this. Json file?

1. Got a load failed error while debugging.

If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 12.6.0.00029)

2. 2. Also, when I attempted to flash the code in UART flash mode according to the flash guide LINK , it halted in the second instruction. (--operation=flash-phy-tuning-data)
Could you kindly advise me on the reason of the problem and how to fix it?
