Hi,
I'm trying to upgrade the firmware of the PSoC™ Automotive Multi-Touch CY8CTMA140 without using the SOC programmer but through I2C interface. I have got the firmware files "ZXXL7C.hex" and "CT5138V01.hex" (each of 70.8Kb size) from Truly vendor.
Following are the issues when I try to upgrade the Firmware,
Reading the Firmware version:
1. I’m following the below mentioned sequence
W 24 00 00 FF A5 00 01 02 03 04 05 06 07
W 24 11
Then when I read, I got 0x85 0x00 as firmware version, after programming the new firmware ("ZXXL7C.hex" and "CT5138V01.hex" ) I’m getting same firmware version.
Updating the firmware with “CT5138V01.hex” / “ZXXL7C.hex”
1. I’m following the below mentioned sequence
W 24 01
Read back BL_STATUS bit4 – Not set, Retry for 10times with delay of 30ms
W 24 00 00 FF A5 00 01 02 03 04 05 06 07 – Flash command initiate record – Passed
Check_record
Prepare_record
Flash_record
Note: During Flash record I2C write passed only when we set the I2C speed in 100khz and it fails when we set the speed as 400khz
After flashing when I test the multi touch the second PSoC™ Automotive multitouch coordinate comes in junk values (Eg: x – 1900 y – 1000) also this values is not consistent. Is this “CT5138V01.hex” / “ZXXL7C.hex” the correct firmware that I have programmed in the device?
2. After Programmed the new firmware, restart the device, PCT went back to old state Second touch coordinate always remains (x – 0x00 y – 0x00) and no junk values. Is it need to program the new firmware each time after booting or it is one time programmable?
